Hi Etimov, Understood that to us assembling parts that IPC is king, however it isn't neccesarily the bible for design engineers. We've had customers demand almost zero voiding, or had to use conductive epoxy to avoid it. For some of us solder joi

It's the same thermal issue whether it's a die or package. It's different if it is just a signal trace, but if it's a heatsink pad (LED, FET, Motor driver, PSU IC etc). I think the voiding issue boils down to what the part is actually doing. The or

Is there a way to make an optical inspection (polarity and shorts test) of a A6284KLPTR-T-1 that has a FK 244 08 D PAK heatsink on top? Is this possible with an AOI 3D Cyberoptics SQ3000? http://datasheet.octopart.com/FK-244-08-D-PAK-Fischer-Elek

The TF2800 features a much more powerful 1900W bottom-side preheater which incorporates 7 independently activated (via software) IR emitters. The preheater is also height adjustable to allow it to get closer to the pcb to provide more aggressive ther

Hello all, Our company has always used HASL finish on our products. Recently however, we have a had a problem on a couple of boards that I have been told cannot be avoided with HASL, and we should switch to ENIG(electroless nickel immersion gold).

| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

We sell rework stations for all kind of components and boards. The systems are designed to fit a particular size board and it's very difficult to design a one size fits all system. I personally have a lot of experience reworking high mass, high hea

O.K., I give up. I am through trying to solder thermocouples on to 20 mil pitch QFPs. Whether it's my lousy technique (fairly likely), the wrong solder (Kester calls it thermocouple solder, and who am I to argue...it's a Sn10Pb88Ag2 alloy) or just
