I think she might be more on track about the air flow. I would think they not only have thermal mass but also emit thermal energy well which would add to the dificutly of removing them. I think a Dpak would have more local thermal mass than the shie

Strange as we have had huge problems with Silver in Many different Assembly houses. Mainly with Nitric Acid based Silvers causing blow holes, non wetting and even the Nitric etching away the tracks on fine boards. It has been one of the main problem

DaveF, Please define a "Cp/Cpk capable profiler." Do you mean one that has software that automatically calculates this for you? I do this at my company, and we track 2 critical variables - Time Above Liquidous and Peak Temps. and this is done on a

Mark, the only Panasonics I've worked with were MSHIIs and an MPAV2B and at this point I'm foggy on both, but both tracked component inspection errors quite well. You should be able to tell how many parts are rejected for thickness inspection errors

The Philips Orion (Yamaha YV100) Head I/O Board is usually at fault as this tends to suffer trackwork problems with age due to the constant flexing of the board stressing the connectors on the board, thus breaking tracks within layers. You should not

Amen to that!! Too many people lately trying to "get out" of rolling their GD sleeves, attaching thermocouples to the board (using their own preferred method), and running the board and profiler through the oven. I'm sick of questions like "duh, pb
