Hi Just had to poke back at this one. Good article David F, Thanks!! A little old yet still great. Hey ever used Pease Porridge from EDN. Modelling has come a long way in a short while, yet still the real physical reality and the desired electro

we are turning on the printer, suddenly the printer is off after checking there is solderball on pad capacitor component 0603 our question is what can a solderball stuck on one pad can when melting and causing shortsolder (being connected with other

Hello. I have a customer that continues to have problems with their bulk cassette feeder. The customer is complaining about shorted parts that result from bulk cassette feeding operations. They are quick to claim that the failure is related to the

I am looking for a rule of thumb regarding the maximum ramp standard components (chip capacitors) can tolerate without failure during the reflow process. The standard seems to be 3C\second, but this figure is generally derived from the average ramp

Sorry i didnt explain it vey well,the parts that are misaligned are always sitting next to these particular tanatlum capacitors.It affects 0805 parts and A tsop36 and can even cause a short on a bga right in the corner where the tant sits.If you chan

I am curious if anyone can help explain to me the cause of an effect we are seeing with some failed caps. The parts have been found to be cracked and in most cases are hard failures (capacitance well out of spec and DCR less than 100 ohm or shorted)

James, What type of profile are you using. Ramp-to-Spike, Ramp-Short Soak-Spike, or Long-Low Spike? I had a similar problem in a past life - random skews on chip components - and got rid of it by converting to Ramp-to-Spike (the old profile was R

| Can someone please advise me to the rework procedure for removal and replacing Ceramic Chip Capacitors (e.g. 0805, 1206, etc.)? | | Is it necessary to pre-heat ceramic capacitors before soldering them onto a PCB with a soldering iron? Is this just

Let me just shortly explain why do I open this thread. In my corporation in different plants we use same components at the same machines in different products(Fuji machines). I would like to create kind of global database of shapes ( its in FujiFlexa
