I have a copy of the Juki catalog "e" and it shows the 750 capable of 0201s but not the 760. We have several customers that get 149s from us to place 0201s. We have also made a custom 101 with one small hole for several machines that would not re

Looking at the data for the 3748 material it says its only heat resistent to 79 C. Im going to go with the 3779 instead because of the higher temp rating (149C). Thanks JD

First I apologize for my poor English writing. we have no heat sink fins and active cooling with power module. when the board is transported,the vibration of board and power module will shotten the solder joint lifetime. if we just solder it withou

We have the occasional solder fine but the main issue I have is with small - large balls of solder around an 0402 capacitor. Our LF paste data sheet states a %rH of 25 - 70, I have recorded an average for March of 14.9 - 38.5 %rH. Every other requirm

We always have big power modules on the board,they are very heavy,so we use the screw to fix the soldered module,then we destroyed the solder joints.If we screw them first, the board can't be wave soldered. My questions: whether we should use the s

I'm not exactly sure of your problem...but I'll give it a shot. I assume the screw is on the solder side of the board. If you wave solder the screw the head will fill in with solder. Try a water solouble mask or peelable laytex mask over the screw
