The Universal chipshooter (Sanyo) has automatic X-Y pick-up correction as standard. Are the upside-down resistors an issue for inspection purposes? Do you use AOI? Can you really read markings on 0402 resistors?

Does anyone know of anywhere alternative to Topline that do all white 0402 resistors on reels for things such as calibration.

Depending on the vision, there might be issues with small black parts (like 0402 resistors etc.) - we have Mirtec MV2-HTL, btw.

While investigating a routing study for a new bga device, I found the vendor used round 20 mil pads on 0402 decoupling caps.This allows fitting the caps between break out vias on their 1mm pitch BGA. Round pad gives about 8 mils diagonally from pin t

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 need help with placing 0402 resistors 90% of them are picked correctly, but are not placed(thrown away) giving me error : LASER retry over. Slightly higher varistors in same package have slightly better placing rate, about 50%, but still not su

We have a PCB rework dilemma involving a reflow profile. This is a SAC305/Low Solids (aka no clean) process where we are currently hand soldering (5) components that were DNP. The boards have an acrylic coating and we take off the acrylic at the par
