Indium has introduced a full line of soldering products that satisfy IPC’s J-STD004B which has stricter requirements for measuring halogens and electromigration risk.
The company’s full line of PCB assembly products was specifically designed to meet these new international standards, which help to improve both first pass yields and long-term reliability.
Indium warns that while users’ existing solder products may meet the existing J-STD-004, they could fail to meet the more environmentally realistic and challenging requirements of the 004B electromigration test.
Included in the new assembly products that are ‘B’ compliant are Wave Solder Flux WF-9948 and Flux-Cored Wire Series CW-807.
Wave Solder Flux WF-9948 is a high-activity, no-clean wave solder flux designed for use with through-hole and mixed-technology assemblies. It performs well with both tin-lead and lead-free solders. It is very heat stable and has been thoroughly tested for selective soldering and wave soldering applications. Even with the high degree of activation, WF-9948 passes all known reliability requirements.
The CW-807 Flux-Cored Wire Series has been fully tested to J-STD-004B. The series includes CW-807 (halogen-free, ROL0), CW-807M (slightly more active, ROL1) and CW-807HMP for high-temperature applications, such as automotive and down-hole survey equipment (ROL0).

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
