Hello, Could you please tell me how you define a defect to be a mass one? What is a criterion? Numbers? How to distinguish between a set of simple defects and a mass defect? What metrics you use? Any input would be appreciated. Thank you in advanc

Hello! We are having field failures due to cracking of the solder on our SMD micro switch components. I have been reading the IPC standards, and the only thing that it states regarding the solder profile/amount for Gull Wing component is "wetted fill

Well yes except it's marked M1 on the PCB, suggesting it's exactly what it looks like, a metal oxide varistor or 'MOV' specifically one rated to 130VAC making the board itself an AC product that takes 110V input. To replace, find any 130v varistor o

I have design some PCBs but last time I met one problem they said missing the solder mask ...any one can give some suggestions why do some pcb manufacturers reject gerbers due to missing sodermask?

Hello, I recently purchased a Hotflow 3 oven, using a step up transformer I received with unit, 220v to 480v. Unit turns on but does not heat up. Getting an F02 error saying no convection. I am getting 480v to oven, I also switched the phase still

Hi Every one, Thanks in advance for your help and support. I am getting errors 'Nozzle pick up error' and 'Nozzle release error' on Mirae Mx350. I have been told to calibrate Nozzle Holes using 'ANC' option in the Menu. Ther

I'm wondering if anyone has ever done a before/after test on the wipe-on type to see if it's any better. The factory applied stuff has been a game changer for us and as already stated, has the added benefit of a dye to indicate that it's still ther

Hello all! I am in desperate need of some Maintenance / Parts / Service manuals for Assembleon ITF feeders (All sizes) Do any of you have them in PDF form I could get? I would be eternally grateful! Also, does anyone know the pinout for the 12v on th

If you refer to having wrong resistor or capacitor value, the only way is to automatically measure the part value. Mycronic pick and Place machines do it on the fly, ASM machines have feeder where part is measured....other main brands probably have

A solution that could placed on any machine is a first check that places a component in a fixed location and then the 2 pin component is read with a meter like a HP component measuring system. Similar for transistors and FETS. IC's are probably not s
