Matte solder mask greatly reduces the potential for solder balls, and since you altered the machine parameters with no improvement it might be flux related. Do you use a VOC free (water based) or alcohol based no-clean flux? Do you use machine settin

When I see that on ours, I take the nozzle off and clean the tip. Any build up and the machine throws that error. Do a set check on the head and then look at the image of the nozzle in question...OR we hit resume and the machine ignores it until the

Hi All, I have some question about flux residue resulted from non clean process as following: 1) Under what kind of circumstances that flux residue could appear? This residue does not happen during production but did appear after some period of ti

Kerryn, It's the first time I hear someone who needs an automated inspection machine to check the cleanliness of stencils. Why not improve on the cleaning method itself. I use ultrasonic batch cleaner. It takes 3 minutes to clean a stencil, 2 minutes

Hello I'm just study PCB in my company. I found many Surface PCB have some contaminate and can not specify what it is. Size is around 2 mm2 . Sometime I send to supplier and they said it is solder paste or some dirty flux. please see contaminate1

You should also remove all the pump parts and clean them, checking the bearings and seals. Clean completely the parts that allow the solder to flow back into the pot; ours have a spiral that fills with dross. Treat yourself to new nozzles. Tinning

The majority of the time, all 4 lines are running 24/7, but it is a big juggling act with the parts. What�s clean, what can be move to another line etc.

Vapor phase or vapor degreasing cleaning for electronics is simple technology that holds merit on process situations like you described. Easy and quick to set up and process with today's modern equipment you can be up and running in no time once the

Ron, you need to check all the thermal couples are in good shape and clean before ask the outside service to do the calibration. After the machine calibrated and I suggest that you run 2 profiles and all the heating zone set at the same temperture,

Hey Guys, We are looking to set up a line to manufacture low volume high mix PCBs. We have work in the display technology and military sectors. Part tracking, lot tracking are critical. The machine may also end up in a class 10,000 or 1000 clean room
