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 -

Typical idents are as follows, but not limited to:- 5% 3 digits, first two are significant figures, third is number of zeros and letter "R" is decimal point. 1% 4 digits, first three are significant figures fourth digit is number of zeros and lette

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

What is the level of interest in bulk feeding cpassive devices, caps & resistors, 0402,0603,0805? The component mfgs. tell me in 3 years 40% of the passive caps will be bulk fed. Their is currently about a 10% cost savings with bulk over tape & ree

Hello, We're experiencing about 4% loss of parts (primarily 0402 caps and resistors, few 0603s and 0805s), and the error codes are mostly 12040403 and 1CA0A009. The help manual on error codes is cryptic at best. Can anyone help me interpret these

It could be a part height issue. I have seen a case where an 0402 resistor from 2 different manufactures had different heights. If the height of your 2010 part is taller than you have programmed in the package data, the pick up head may be pushing

If you are sure that your part data is correct, have you checked the calibration of Z origin? Are the parts leaving an impression on the paste or is there no indication of an attempted place. How small of resistors are we talking 0402, 0603, 0805?

My experience with SMT LED packages is that certain LED package styles tend to float. This floating is caused because the LED is often only terminated on the bottom side of the LED package. Sometimes the LEDs are terminated like a SMT resistor with
