I am trying to figure out how many feeders I will need for our first venture into SMT. I have broken down our largest board we would build into the different feeder types. What I need to know is, how many extra should I order? Why?

CTE mismatch. X, Y, Z all expand at different rates. Cooling or heating rates will not change this CTE mismatch. Layer counts, power plane ballance, equal run lengths in x-y and copper balance all contribute. Have your supplier evaluate your s

Do a dirty DoE...print ten boards with the worst error you think you can accept, build them up, and count print related defects. At the same time, print ten spot-on and proceed the same. If you don't have any more defects on the off-print batch show

I agree with AVFM. We have had at least 5 TP machines and a MY12. We stick carrier tape to scrap circuit boards with double sided tape. Teach it as a tray. Works perfect. The Count On strip feeder looks cool but is no necessary in my opinion.

Hello Our production face a problem where our board after etching become shrinkage till 0.09mm but sometime it can be till 0.18mm. this happen after etching still the beginning of process not count for silver through hole and carbon process where th

The layer count itself isn't going to be what drives yields. What is the trace/space? How much annular ring for vias did you give them to play with? Class 2 or class 3? What's the worst hole aspect ratio? Controlled impedance? The closer you run to y

Have you heard about the stamp soldering solution for THT? With a 25 second tact time maximum, for any size board and regardless of the THT component count, and much better yields than a fine tuned SMT process, stamp soldering can remove the largest

Sounds like your talking very low volume & component counts really... I would look at Panasonic AM100 for example - low cost, high flexibility but you would need multiple so you could pair it with another... Ideally we would need to understand your

I have been in smt for about 4 yrs. I would say you need to evaluate what type of components you are going to place. How many boards your orders will be for. I use Quad pick and place equipment. These are all around good machines for placing everythi
