Chris, one question, which standard allows to put it in the drawings/dokumention? As I said in my old IPC-D-275 it says "no". Did it change with the new edition ? Referring to J-STD-001 in this case seems to me like "I followed only the orders and do

In a similar conversation ... Alex Krstic, NovAtel Inc. said ... Hello all. We recently received some boards with some of the chip resistors placed with their resistive elements towards the board. J-STD-001B and C view this as violation for both Cl

I only inhale flux with a high IPA content.(joke for those who don't know me) I have seen the inside of duct work for our wave soldering machine............NASTY! DAVE F. is right! Flux contains a lot of bad stuff- Chlorides, Bromides, Flourides,
