dering practicing and training or for machine-run applications to evaluate, validate or qualify equipment, prod- uct and manufacturing processes. Components for hand soldering


will be bagged and labeled and in a box for classroom training. Machine- run kits will have the components packaged in tubes, or on tape and reel. Practical Components also offers cus- tom board design, custom board fabri- cation and board assembly, if the cus- tomer requires these services. The company provides ad-


vanced test wafers, which are daisy chained or for wirebonding and can be supplied diced or as uncut whole wafers. The company offers 6, 8 and 12 in. (152, 203 and 305 mm) wafers, as well as matching substrates in a variety of pitches from 20 to 200 µm. These test wafers are offered with Cu pillars with SnAg solder caps, SAC305 bumps, Ni with SnAg plate, or with no bumps. The chips can be used for stress


or thermal resistance analysis, mi- gration testing, bondability checking, micro line evaluation, or stacking with TSVs and silicon interposers. Practical Components also offers glass die and wafers with Cu pillars in 150 or 200 µm pitches. In addition, the company offers


a wide variety of SMT and through- hole components, test boards, hand solder training kits, and kits for all types of evaluations, validations, qualifications, and DOEs.

“It’s very economical and provides a ton of value. The company was flaw- less at installation, set up and train- ing, very hands on. People do busi- ness with people not companies, and they’re easy to do business with. They’ve got my back.” Back on the basketball court,

But, for everyone involved, the


ShotTracker system relies on those precisely constructed PCBs function flawlessly, delivering just what every- one involved has come to expect: de- tailed, accurate and instant informa- tion that enhances player performance and spectator enjoyment. Contact: East/West Manufactur-

eWLP and CSPnl dummy wafers from Amkor Technology. Both the eWLP and CSPnl wafers can be purchased as uncut, whole 8 in. (203 mm) wafers or diced. The eWLP has copper-embed- ded pads 8 to 10 µm in height and the CSPnl has SAC405 bumps or can be delivered without bumps. The eWLP and CSPnl wafers


the SMTA solder paste test vehicle and kit for miniaturized SMT, which consists of test boards and compo- nents. The kit includes 0.01 to 0.02 in. (0.3 to 0.5 mm) pitch BGAs, 0.016


can be ordered in many different die sizes from 0.03 to 0.2 in. (0.8 to 5.6 mm). Each wafer can be diced in one specific size and each die is daisy chained. The standard wafer thick- ness is 725 µm and can be back ground to 200 µm. Besides the test wafers with Cu pillars, the company is also offering


The same manufacturers that create the live components make these dummies exactly the same, but without the expensive live die. Practical Components distributes components for most major manufacturers.
