Hello everyone. I would like to know opinions about which is the best SMT machine (pick and place) on the market, for smd electronic manufacturing, to put 0201 chip-type components up to large packages, such as coils, capacitors, soic16-, QFN, BGA et

I recently encountered reflow soldering defects on a pair diode package, the smd pad had a green contamination, I'm convinced that this is not oxidation. The no-solder condition appears to be caused by a sloppy soldermask process, although over the y

Traditional methods of hand assembly are as you described. For a company that is concentrating on the 1-5 or 5-50 quantities you've described, you need to look for ways to accomplish your task with speed, repeatablilty, quality and at a fair price. T

Assuming that you have a saturated moisture-sensitive component: At what temperature would popcorning or internal component damage occur? I would guess that it would be at a temperature where water would boil, around 100 degrees? However, the JEDEC J

I have many PCBs that use an AVR in SMD packaging, and since I frequently change the firmware in prototype boards, I'm trying to come with the best solution to program the AVR quickly and easily. The first approach was to have a standard header (2x5

Hi, if you do only contract services I`d advice own part numbering. All I can say is just try to create each cathegories which will contain other cathegories and so on. Applying this system will make some order in your stock. For instance : RETR020

John, Maybe you know this already but I just wanted to highlight a few facts about dry cabinets. My experience is that many engineers are not well aware of the industry guidelines and sometimes will buy a dry cabinet without understanding the key f
