Hello! SMT professionals, I do not know if anyone posted this question before. Last week, I reflowed our newly designed thin Rigid-Flex pcb with 0.040" thickness. I found all of pins of a TQFP48 ic did not get wetted. I could see on the heel side o

Hi there. We have had an out of control reflow oven that has allowed its temperature to fluctuate by up to +/- 20 deg C from set point in very short periods of time. We found the root cause of the problem and fixed it, but by then we had already run

We are a military contractor and need to build to IPC610 class3. We are receiving many parts with palladium leads and currently use a No-clean solder paste. We have evaluated OA pastes with very little improvements. Without a touch up of all leads th

Steve, TI does not produce any SOTs using Palladium finish leadframes. I would certainly be interested to know who is. Also, your observations are correct: In TI experience the mechanical strength of the solder joints with Pd finish ICs is alw

I snapped a board in half at a cracked solder joint, and the component pulled free of the solder and still has a very thin layer of metal on the termination end. Based on the construction spec.(solder over nickel over palladium), it looks like it

Are we possibly talking palladium instead of platinum? I haven't yet heard of platinum terminations (seems expensive) If it is palladium over nickel, I can tell you that you need to reach 225-230 Deg. C in reflow and the TAL should be about 90 sec.

Hi everybody, I found a defect varistor 0603 Tombstone and poor welting when we use component that terminal is Silver palladium (Ag/ Pd) with Leaded solder paste (63/37). Then we change alternative component that terminal is Ni/ Sn the result not fou

Anyone using ENEPIG electroless nickel electroless palladium immersion gold? Am currently using selectively plated gold 25 micro inches in combo SMT/COB gold ball bonded product. Gold cost has increased over the years. Palladium cost is much lower

I am interested in the opinions of those who have done experiements or have experience with HASL, OSP's, Palladium, Ni/Au , and White Tin PWB plating. Based on your experience please give me the pro's and con's of using these plating options. Thank

| Yes, norm it is. Look back to February 98 :discussion on this issue. Norm, That discussion does deal with palladium coated leads, but when I read your statement about silver/palladium fired terminations, I'm assuming that you're referring to
