as someone had said before, check you stencil and have it redesigned. I design our stencils for my factory and have inproved quality in BGA , QFP and 0603 case sizes. we did have 1 prototype series that used 0403 chips btu we had brand new feeders an

Thanks for the quick reply :) We've used some classic feeders that we repurposed ourselves by switching the original optical barriers (index wheel and motor wheel) with twice the resolution. It gives okayish results, not great, but the 0402 is alig

I am using SiPlace S20 and F4 machines. Both of them handle 0402 without problem. A newer machine, like S23 or S25HM is way better and accurate, S27HM can place smaller parts too. We are using EKRA E5 (2000) which can print this size without issues.

I am looking at buying a pick and place machine to assemble the circuit boards we make. Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC

Need all your experts out there for tips & tricks to make things work. I been giving a task to help redesign a simple board; only to load two components. The challenge is to use pick-n-place machine to load the coil onto the 50up array panel. Previou

Maybe you have to contact your machine support they can modify special nozzle for that component...i dont know what else you can try...or just contact your support and ask them what to do...we had a similar problem with LED diode on our machine..and

Is ur smt machine not able to pick 0402 componets? We use Yamaha SMT for 0603,0805,ect. We just change nozzle and feeder in the same machine when 0402 is needed to mount. by the way, we use not only new machine but 2nd hand also. there is a few sma

My company also uses the TM8C (all feeders) with the same problem as Paul. The 0402's do exactly the same as he desribes.The SMT operators are correcting the placement data all the time when using 0402 but to no avail. Chris What do you mean by the

Verifying pick height is a good start. Are you using the proper nozzle (81) and feeder (yellow)? How was the comp lib created? If you continue to have any problems, I would suggest copying an 0402 from the master library. You can also call UIC's tech

For 0402's, if the operator is paying attention, our equipment Panasonic CM 402/602/NPM's run at about .001%. Again this is dependent on an operator that pays attention to the fail rate. We usually don't have too many problems with 0402's, LED's ar
