Cobar No-Lead and Flux Brush at APEX Hand Solder Competition

Breda, Netherlands — The Balver Zinn Group's Cobar Solder Products Inc. supplied soldering materials for the recent hand solder competition at the IPC APEX EXPO in San Diego.

During the two-day hand soldering competition, numerous companies competed to build a functional electronics assembly in 30 minutes. Assemblies were judged on soldering in accordance with IPC-A-610E Class 3 criteria, the speed at which the assembly was produced and overall electrical functionality of assembly. IPC-A-610E Master Instructors served as the judges.

SN100C is a high-reliability flux-cored lead-free solder wire that generates minimal spatter even with the high solder tip temperatures required to burn off polyurethane insulating enamel. The alloy reduces risk of copper erosion during soldering and slow growth of the interfacial intermetallic layer in service. Additional features include low flux spattering, minimal cracking of flux residue, low fuming and odor, and cost-effective high-temperature soldering. The wire also can be used with soldering tip temperature up to 400°C. The alloy extends the solder tip life due to lack of silver and the presence of nickel.

A precise, inexpensive and handy tool for applying liquid flux to tiny chip components as well as individual solder joints, the Cobrush flux applicator puts flux only where it is needed — in just the right amount — and is suitable for applying liquid no-clean fluxes to any site that needs to be soldered. The tool disposable and compatible with many different types of fluxes. Its fine bristle tip allows the user to apply flux to very small areas in densely populated assemblies. This inexpensive applicator cuts down on waste and prevents overfluxing, thus reducing possible cleaning time and preventing contamination. Its transparent cartridge allows the user to see the amount of remaining material in the reservoir.

Its small, compact size and large capacity make it especially suitable for most rework and post-assembly applications. Flux is dispensed by lightly squeezing the barrel, then using the gentle applicator bristles to apply the flux, just like an artist's brush, which allows the user to control the amount of flux flow. A snug-fitting cap prevents flux evaporation in the barrel, thus extending the life and purity of the flux.
