Soldering Materials & Equipment
December 31, 1969 |Estimated reading time: 2 minutes
KIC, Indium, FINETECH, VJ Electronix, EVS International, and Kester are exhibiting various products from lead-free solders to reflow process controls and rework, to reduce waste and costs and increase reliability. Indium's Ning-Cheng Lee, Ph.D., is teaching a lead-free reliability course.
KIC, headquartered in San Diego, will premier the 24-7 Wave, offering process management such as automatic profiling, real-time process monitoring with instant alarm on out-of-spec situations, automatic statistical process control (SPC) charting, and process traceability, for the wave solder process. Embedded sensors in the preheat, wave, and conveyor continuously monitor temperatures and conveyor speed, and the machine can stop the feed-in conveyor in out-of-spec. operations. KIC will also display its 24/7 process monitor; KIC Vision, an automatic profiling system; and Wave Surfer, a self-contained measurement system for wave solder machines. Find KIC at Booth 2D01.
Indium Corporation's (Clinton, N.Y.) vice president of technology, Ning-Cheng Lee, Ph.D., is teaching a six-hour short course on raising lead-free solder joint reliability, emphasizing implementation of reliable lead-free assembly processes by overcoming technical issues and challenges. He will focus on legislation; alloys, surface finishes, components, and substrates; wave soldering, rework, and inspection, and common problems and solutions. Indium is exhibiting its Indium5.1AT lead-free solder paste at Booth 2H30. The paste offers 5% voiding in BGA with micro via-in-pad solder processes.
FINETECH, headquartered in Tempe, Ariz., is highlighting its Micro Rework application package for FINEPLACER Pico. The product aids in single ball repair, µCSP, and rework on small passives such as 01005s. The Pico helps automate work on misplaced or deformed balls, wrong-sized balls, ball bridges, or blank positions on a SMD component. The system can handle ball sizes smaller than 200 µm.
VJ Electronix, from Littleton, Mass., is exhibiting its PMT400 rework system in distributor KAL's booth B101. The PMT400 targets rework of microBGA, BGA, CSP, SMT, MCM, and THT assemblies. The rework system is lead-free capable; included software is reportedly simple and intuitive. The Nepcon appearance will debut this rework system to the Asian market.
EVS International (Isle of Wight, U.K.) is demonstrating the EVS 1000, a smaller, lighter version of the EVS 3000/6000 standard and lead-free solder-recovery units. The smaller size and footprint provide a capacity of 10-lb/5-kg of dross, and are said to reduce costs. Find EVS at Booth 2H06.
Kester (Itasca, Ill.) features its low-cost, silver-free Ultrapure K100LD lead-free bar solder alloy at Booth 2G30. The lead-free alloy primarily contains tin and copper with the inclusion of metallic dopants to control the grain structure and copper dissolution rate. The company will also display its EM918AP lead-free, no-clean solder paste, which boasts slump resistance and similar appearance to tin/lead alloys post-reflow.
