I agree with the other comment, if you have misprint something is wrong with the screen printing process, meanwhile try to get a ultrasonic cleaner for your boards, another thing you can do is to use dummy boards, if you don't have a lot of different

Please check the solder paste height near PCB edges, Please check board clamping during solder paste printing. Please check tooling support boards must be fixed during the printing process. try to set wiper cleaning frequency and fine tune for best

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture

Hi Thomas, Thank you for your posting and I agree with you that Printing is the most difficult one. BTW, after you ran the one side (let's say Bottom side), my engineer worries about the distortion of flex board because of the thickness. In that ca

Hi, I work at an electronics manufacturing company and right now, we are selecting a new screen printer instead of our old Samsung SP-450. Does anyone have some experience with these machines or at least manufacturers? These ones are basic and sim

I've never seen successful printing with a step as deep as you seem to be saying. The keep out would have to be jigundous!!!! SMTnet Technical Library: https://smtnet.com/library/files/upload/Step-Stencils-laserjob.pdf I'd guess * Maximum step

Hey guys, my DEK265 GSX is acting funny. It misprints half of the boards. The one half when squeegees move away from operator to be precise. When squeegees are moving towards operator print is perfect. In both cases actuators are moving prior to prin

Alrighty... Problem solved - ended up not being a problem at all. So, what I didn't realize, was that the knead pressure was 5kg, and the first print was always kneaded, so that's why the set pressure showed 5kg. After it was done kneading, the set

Pretty much paste dependent on what is required. I am not a huge fan of kneading unless absolutely necessary, so 15 minutes seems pretty short, and generally do only 2 strokes. Multiple print deposits is used when, for whatever reason you are not see

From the picture, I cannot see clearly solder ball violate electrical clearance or cause a short, maybe it is. What I can see is the solder paste has some misalignment although it doesn't printed in solder mask area, but actual position will reduce
