Question: Does this formula apply even for the small LGA:s like LGA36 6.5 x 3.5 x 0.6 mm pad size 0.35mm pitch 0.60mm? We use a 0.13 mm stencil thichess beacuse on the same board there is some P.I.P comps. The board dimensions is 35 x 50 mm on a pane

Greetings, I would like to do a height calibration, because the laser of the machine seems to be out of control, I'll explain why: When I measure the height of a 0402 resistor, I get around -0.60 to -0.70, when I fix it on what the machines has measu

Hello, mcdvoice It seems like your Juki RS-1R machine's laser height calibration may be off. When measuring a 0402 resistor, it consistently reports heights around -0.60 to -0.70, causing pickup issues during production. Manually adjusting it to -

| | Hi, | | I just cheesed my previous attempt at this. I looked through IPC 600 and couldn't find anything relating to dimensional stability of a board with regard to stretch. I found bow and twist but nothing on size. I have a PCB that is .030"

Russ, Your math is right, but you are converting the wrong direction. I belive: 0201s use millimeters for specification sizes, not inches. And 01005 use millimeters for specification sizes, not inches. And it may be like that for all passives, bu

Absence of solder is just black/super dark red which still falls under any percent I could put in there. So it passes. Maybe I'm a bit confused on how the machine checks solder in general anyway... 0%-60% is a pass by default. Thats anything dark - s

I have been doing this since day one of getting the AOI. It just seemed logical. I don't know what type of AOI you have, but what I have found works best is to use solder inspection to catch parts that are loaded into a no-load location. Move the
