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

There's a lot of parameters to consider in defining stencil life cycle. Average squeegee pressure used, in-process cleaning frequency (auto and manual), physical appearance over time, tension reading over time, and so on to decide how many print cycl

For height, I start +-2mil usually. For 3mil stencils, my lower limit starts at 1.5mil, upper is 5. If the area is chem ethed, I normally add .5 to the stencil height. My default volume is 60 - 160%. Then print specs are adjusted till I see fit, then

Hello guys , For our SPV machine (Printing machine) , am looking for flexible support pin or some other idea to support PCB during second printing process ( Double side process) . We actually using ( 1: stainless steel support with voids for mount
