Flux Cleaner

In the metallurgical industry, is used as a flux for soldering applications. It is used to prevent metal parts and assemblies from oxidizing during the heat-treating process. Commonly used for soldering electronic parts, creates a barrier between metal workpieces and the heat source that’s used to perform the soldering operation. This scenario is essential for keeping metal contacts from oxidizing and causing costly repairs for unanticipated electrical problems.

According to Wikipedia, flux that is commonly used for electronics “has about 1% () as a flux core helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer [that is] formed at the surface back to metal. When the heat-treating process is complete, leftover () is frequently as the burnt or clear residue that [surrounds newly soldered] electrical parts.” This description of soldering inherently underlines the importance of using a high-quality) flux remover on affected electrical components.

Using () Flux Cleaner

() flux remover is formulated to remove the “burnt or clear residue” that () flux leaves after the heat-treating process is complete. When () is used as a flux for soldering electrical contacts — particularly those that other precision components tightly surround — using an aerosol  flux remover offers several benefits over using a flux remover in wipe form. Below are some essential benefits of using an aerosol solution instead of one that is wiped on by hand.

·          Easier to control dispersal of the solution

·          Less waste flux remover in the waste trap

·          Easy to implement and put directly to use

·          Even dispersal of remover on affected parts

A small amount of () flux residue that surrounds electrical contacts may not seem to be a major problem to the casual observer. However, there are several reasons to remove the accumulation, with the following reasons being highly crucial to the operation of the equipment and its acceptance by customers who need to use the equipment in a business-critical capacity.

·          A () shell may cause contacts to become hotter than usual

·          The chemical consistency of () may cause contact corrosion

·          () on contacts may cause customers to reject the product

·          Depending on its properties, () make attract dirt and grime

For these reasons and others, it’s important for metallurgists that use () soldering flux to use a () flux remover to remove excessive accumulations of () -based flux residue, too. If your company is looking for a chemist-created () flux remover, () that is available from ()  in aerosol and liquid form may be the perfect solution for your work processes.

Static Eliminator

The static eliminators are products that protect susceptible items from the effects of static discharge. These static shields are also known as antistatic (anti-static) devices, anti-static electricity devices, or static charge eliminators. They work by dampening, reducing, or otherwise inhibiting its buildup or discharge.

Static eliminators or static ionizers eliminate static and dust and can neutralize and clean surfaces at remote distances. Static neutralization is a practical method of static reduction; however complete static elimination is not readily attainable. In its simplest form, a static eliminator or static ionizer is a static reduction device that produces positive and negative ions which are attracted to an unbalanced surface or material. As long as friction is not reintroduced, static electricity remains at minimum levels. Since static eliminators vary in terms of capabilities, a careful consideration of performance specifications is an important part of product selection.

Application of Static Eliminators

Static electricity is a stationary electric charge imposed on a solid surface. The solid surface either gains or loses electrons by interacting with other materials or surfaces, most commonly after any amount of friction has been applied. The resulting surface will have an excess of either positive (+) or negative (-) charges that attract opposing charges and repel like charges. The study of stationary or slow-moving electric charges is known as electrostatics.

The electrostatic forces causing attraction and repulsion can be explained by Coulomb's Law. Coulomb's law states: "The force of attraction or repulsion between two-point charges is directly proportional to the product of magnitude of each charge and inversely proportional to the square of distance between them."

Static eliminator are used to eliminate static and dust. Static electricity is a problem, which companies face globally. It primarily affects industries, which handle nonconductive materials like plastics, paper, board, laminates and textiles. The electrostatic attraction repulsion cause materials to stick to machinery, or to each other, leading to jams, slow machine speed and poor quality and productivity. Friction, pressure and separation are the major causes of static electricity. When humidity is lower, higher static charges are generated. It becomes more noticeable in the months of winter, in dry laminates, and in air-conditioned environments.

The static eliminator safety and compliance standards, laid down a framework for devices and there is a need to adhere to depend on your product, industry, and location.

International Standards and compliance

Other organizations in the world that issue static eliminator standards include the military (Mil-Specs), the ESDA (Electrostatic Discharge Association), ANSI affiliate, the NRC (Us Nuclear Regulatory Committee), and the FDA (Food and Drug Administration).

Also, the International Electrotechnical Commission (IEC) has been putting out standards for static eliminators related to electrostatic discharge for customers around the world since the 1980s. We highly recommend making sure that your supplier can make static control products that meet IEC standards before agreeing to work with them. For information on the best standard requirements for your application, talk to your industry leaders.

Our ergonomically and precision forced static eliminators design are fully compiled with international standards and norms to deliver best and reliable quality and focus for our customers spread across the globe.

Soldering Station

The Soldering Station is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons less commonly used today than in the past were simply a large copper bit on a handle, heated in a flame.

Desoldering Station

Usage of Desoldering stations range from very minute straight-forward jobs to heavy-duty applications. Based on the requirement and application, different stations are available, varying in power consumption, temperature range, microcontroller (MCU) based control and other features.

Contact Desoldering stations are the most common and popular kind of Desoldering stations. These have a built-in power supply unit, which, in most cases, ensures the galvanic separation between the power circuit and the heating element. Voltage on the heating element can be adjusted using the power supply unit and the heating temperature can be changed accordingly.

Features of Desoldering stations

Lead-free Desoldering station are another category that is used to wire lead-free printed circuit boards (PCBs). These usually make use of lead-free solders and are not necessarily expensive. With many developed nations making regulations favoring lead-free Desoldering, these stations could come in handy for future applications. Lead-free Desoldering stations are specially designed for working with lead-free solders, which offer good reliability and good solderability.

Although, lead-free stations have their own share of cons such as requirement of extra heat to melt lead-free solder, which, in turn, affects the tip of the Desoldering iron. Most of the reputed manufacturers educate their buyers on ideal usage of lead-free Desoldering stations, which helps them maintain and extend the life of Desoldering tips.

Additional perks

Desoldering stations are also packaged with different kinds of heaters. Ceramic heaters, induction coil heaters and combination of heater, sensor and Desoldering tip integrated into one tool are some other variations in Desoldering stations.

Hot-air rework and Desoldering stations are generally used for removing components from PCBs and re-Desoldering new ones. While rework stations are ideal for simple jobs, Desoldering stations are mostly used for demanding reworks on PCB boards and are comparatively less expensive.

Hot-air Desoldering stations are optimum for professionals and hobbyists because these can be used for preheating components before removing or can be used to reflow SMT components such as dual inline packaging (DIP), small outline integrated circuits (SOICs), quad flat packages (QFPes) and other ICs.

Desoldering and Desoldering stations are a must have for all electronics professionals. Nowadays, all stations are electrostatic discharge (ESD) safe, Restriction of Hazardous Substances (RoHS) compliant and digital in nature, the new-age Desoldering station offers digital display, digital calibration and password lock functions at a very competitive price. One of the recent developments is the induction heating-based hybrid Desoldering station. These stations use the benefits of both technologies, IR heating technology and convection, to bring out the best in Desoldering.

Hot-air stations are coming with built-in turbines for easy repair applications and heating processes such as shrinking. Brushless turbine is incorporated for ideal hot air flow such that hot air temperature is controlled electronically. Benchtop Desoldering or rework stations have the most accurate temperature controls, best thermal recovery and additional features like programmable timing. Desoldering stations come with (XX) Technology Desoldering iron tips. These low-mass tips provide effective heat transfer via its silver core.

SMD Rework Station

Rework (or re-work) is the term for the refinishing operation or repair of an electronic printed circuit board (PCB) assembly, usually involving desoldering and re-soldering of surface-mounted electronic components (SMD). Mass processing techniques are not applicable to single device repair or replacement, and specialized manual techniques by expert personnel using appropriate equipment are required to replace defective components; area array packages such as ball grid array (BGA) devices particularly require expertise and appropriate tools. A hot air gun or hot air station is used to heat devices and melt solder, and specialized tools are used to pick up and position often tiny components.

The SMD rework Station involve several components, which must be worked on one by one without damage to surrounding parts or the PCB itself. All parts not being worked on are protected from heat and damage. Thermal stress on the electronic assembly is kept as low as possible to prevent unnecessary contractions of the board which might cause immediate or future damage.

In the 21st century, almost all soldering is carried out with lead-free solder, both on manufactured assemblies and in rework, to avoid the health and environmental hazards of lead. Where this precaution is not necessary, tin-lead solder melts at a lower temperature and is easier to work with.

Mask and spheres for rebelling and working of SMD

Heating a single SMD with a hot-air gun to melt all solder joints between it and the PCB is usually the first step, followed by removing the SMD while the solder is molten. The pad array on the conductor board should then be cleaned of old solder. It is quite easy to remove these residues by heating them to melting temperature. A soldering iron or hot air gun can be used with desoldering braid.

The precise placement of the new unit onto the prepared pad array requires skillful use of a highly accurate vision-alignment system with high resolution and magnification. The smaller the pitch and size of the components, the more precise working must be.

Finally, the newly placed SMD is soldered onto the board. Reliable solder joints are facilitated by use of a solder profile which preheats the board, heats all the connections between the unit and the PCB to the melting temperature of the solder used, then properly cools them.

High quality demands or specific designs of SMDs require the precise application of solder paste before positioning and soldering the unit. The surface tension of the molten solder, which is on the board's solder pads, tends to pull the device into precise alignment with the pads if not initially positioned totally correctly. Our () SMD Rework Station is of finest quality with unmatched features and quality to dominate the industry.

No Clean Flux

Soldering with no-clean flux is a viable alternative for eliminating the laborious post solder cleaning using costly and polluting CFC solvent cleaning.

To eliminate cleaning, the flux and soldering process must:

a) Bind effectively to make sound solder joints
b) Leave minimal amount of residue after soldering
c) Have left over residue which is translucent, aesthetically acceptable and non-tacky that will not interfere in any in-circuit testing, automated pin testing or bed-of-nails testing.
d) Have left over residue that will not react with the circuit or components and will stay inert and not be      influenced by changes in temperature, humidity or fluctuations in voltage.
e) Be economic and practically feasible.

We offer specially formulated no-clean fluxes that meet the above conditions, and are suitable for a variety of applications.

No Clean Flux are low solid (less than 5%) fluxes, specially developed for SMDs and mixed technology soldering. They are completely non-halide, show outstanding solderability on all types of board including SMDs, give excellent wetting on surface mounted components, and leave no visible flux residue after soldering. Often no further cleaning is required, but if very high ionic cleanliness is needed, the residue can be removed by solvent or saponification cleaning. These fluxes are J-STD-004 compliant.
No-clean fluxes with solid content less than 3% are also available for use in foam flux operations as well as application by dipping, brushing or spraying.

Those with solid content less than 2.2% have been developed to meet industry's need for high speed automation and high reliability. The small amount of residue is non-corrosive (meets IPC and J STD requirements) and tack free (meets Bell Core specification).

We also have a low solid-2%- flux, that is halide free, no-resin, no rosin flux, for soldering through hole, mixed technology, surface mount and solar panel assemblies. It can be applied by spray, dip and foam equipment. It meets ANSI / IPC SF-818 Assembly Class 3, SIR requirements.

Voc Free Flux

In an effort to reduce volatile organic compound (VOC) emissions within our environment, policymakers have encouraged and/or mandated that electronics manufacturers change from alcohol-based VOC containing fluxes to water-based VOC-free flux alternatives. As a result, the use of VOC-free fluxes is growing throughout North America, Asia and Europe.

The VOC free flux in the soldering process and their impact on testing is high and product reliability is among best. These factors include; the effect of varying types of acids used in flux formulations and their impact on Ion Chromatography (IC) and Surface Insulation Resistivity (SIR) test results and weak organic acids (WOA) solubility and their influence on the electrical integrity of assemblies. This paper shall provide valuable insight into the outcome of acid-solvent interactions.

The transition to the  VOC-free flux from alcohol-based fluxes can be a challenge and may require several changes in the assembly process. Compounding these challenges is the increased use of lead-free alloys with the looming expiration of the RoHS exemptions. Additional pressure has been placed on solder flux manufacturers to meet the newer, more restrictive ionic test requirements and updated SIR test criteria. AIM Product Development Group's study consisted of using several organic acids, each individually incorporated into both a generic VOC-free and a generic alcohol flux base. 

Half the test boards were sent out for IC testing per IPC-TM-650 2.3.28 to determine the level of WOA. The other half were sent for SIR testing per IPC 2.6.3.7. The fluxes were also run on a wetting balance to determine solderability differences. The test results of the alcohol-based fluxes were not included in this study.

The successful implementation of VOC-free flux technology requires some process modification for most of the existing wave soldering equipment. An increased air flow across the circuit boards is needed to drive off most of the water present in VOC-free fluxes. The purpose of this paper has been to present a modification that can be installed onto existing equipment to help drive off the excess water. The suggested network of tubing is easy to assemble and easy to retrofit onto existing equipment.

The VOC-free flux is of highest industry standards while maintaining a perfect price range is what all the  is dedicated about.
