Hi Lou, If real process control and useful defect data is what you're looking for, Orbotech has some of the best tools available out there.

Just had anopther thought, what type of parts are you using on this board? You may want to try a thin stencil like 5 mil or so this may help you. also can this "tilt" be from a movement during reflow? Russ

We discussed about applying 2 dots of glue on either sides of the LED body, but have yet to try it out. Other discussions include conductive adhesive, using fixturing with weight, different stencil aperature design, hand soldering.

Wouldn;t the glue hold the part up?, usually a glued part has much higher standoff than a soldered one. Russ

Sure would. We discussed applying the glue on the sides rather bottom of the part. Hopefully the seating of the part during P&P helps push it down. Certainly there will be still some gap as some of the glue will be under the part. Each experiment off

Thank all for your advices. But we had sistem error,which was connected,how we could undestand with failure main PC controller boards.We had swoped winchester memory block and Zevatech operation was restored Best regards Peter

Not sure if this has any bearing on the problem but did you check to see that T2 and T3 are jumped on the speed control board per the first note in the prodedure?

What about the relay that controls the heater? I've seen that problem on conceptronics ovens. The relay would latch on and never turn off.

stepheniii Unsure how they determine that the process is stable and in control, a prerequisite to calculating Cp, Cpk. A trained chimp smoking a cigar could calculate Cp, Cpk.
