:s I'd be frightened too if I had SAC305 in my balls.

Most of the semi-con is using SAC305 balls. Only the PCB assembly house feels the heat, but semi-con never feels any pressure.

Hello, Changing from Pb to Pb free solder pot takes about 10 hours. is there any easy way to reduce the timing for this process with additional or new equipment.

Sure is. It's called Dual Pot. Most major wave solder manufactureres offer it. The quickest way is to buy a used wave for Pb and keep your existing Pb free wave, Pb free!

Hi Friends, We would like to know what is the procedure to test Cp & Cpk on Reflow oven at customer place .

CK the Flip Guy You're correct. Some profiler suppliers include a Cp, Cpk calculatoromiter with their very nice units.

Would their calculatoromiters set off my BS detector? It's quite sensitive with things like Cp,Cpk and use of statistics. Or are they actually genuinely usefull?

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.

You're correct. So, you're thinking about putting the PTH parts on the same side as the SOIC LED, making the top into the bottom, right?
Electronics Forum | Sun Feb 11 08:44:47 EST 2007 | jerry
No, 50 parts on one side and 4 SOIC leds on the other. The LEDs cannot go through the wave so I need to mask them off or cover them up to protect them during the wave.
