There is a Chinese software product called "Programming" from Ealead. https://ealead-e.ucoz.com/index/eps/0-10 The Ealead software makes spliting your product over a multi-machine line, even if they are not from the same manufacturer easy! My soft

Splitting hairs, I expect SIR of all solderability protection, including OSP, to decrease after reflow. What�s more, I expect the SIR of all solderability protection to pretty much decrease over time. The �comb pattern� test specimens meet requirem

The basic rule of thumb (info current as of 9/2000, from Ceeris and others) is the 10X multiplier for each major process step. Catching a defect and correcting in SMT will cost $0.10 each. (think about $.04 placement cost, stop line time, operator h

I have encountered problems with a 90/10 tin-lead plated SMT component wicking all the solder paste off the pads on the substrate. Worst, the defect occurs randomly - adjacent leads may have 'good' joints, though heel fillets are poor. The solder pa

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

Calculate numbers according to your situation, as follows: Cost = Cost per kilowatt hour x [Amps x volts x hours of operation � 1000] Cost per kilowatt hour: What we need to do to figure out the total cost is get out our electric bill. Look on the

Hi, I have a QUAD 4C mk2. I taught pickups and places from HHT. If I test them individually (RUN STEP PICK/PLACE etc...) before building the sequence, everything runs ok. After the sequence was built, everything goes wrong. Every PICK or PLACE ends i

I presume the dongles you talk about are for an application called HLC from JUKI. The 2 different versions are for the later 2000 and 3300 and FX series the other key for the older 700 series. There is another way to solve your problem. AN applicatio
