Hello guys, I have a error message in a QSV-1 machine, when it tuns on "File archive error occurred while reading header of table top:permanent table top", I have no experience with this machine, so no good so far, already escalated to service and wa

fluxer => cleaning (or lack there of) => conformal coating: there is a lack of compatibility. You need to figure-out which is the bad boy. Maybe a good guess is to conformal coat boards at each step in the process and then have them tested. Don't de

We us a lot of 1B31 it could be one of the most common coatings out there. We do not clean the boards and do not have an issue. I would check the solder mask compatibly. I would also see how the 3rd party company is testing the boards what criteria o

I'll chime in here as well. If you have adhesion problems, 90% of the time it's contamination on the substrate (soldermask, flux residues, cleaner residues, etc.). Like Dave said, omega meter is a test for gross cleanliness, and it's OK for process

Have you had any luck? I just purchased the same machine and it has some kind of a boot error. After power up a screen pops up in Japanese with English sub titles. In the bottom left corner it reads Memory Card Data Error - Load Data. I connected to

It's bad practice to remix used solder paste with new solder paste in the jar. Further, some would argue that it's bad practice to reuse solder paste period. If economics force you to reuse solder paste, store it for reuse in an empty jar. When rea

Thank very much for the feedback. I was asked why mixing the paste was not a good idea. Could you provide the answer please? It's always better to hear from an outside expert:) The SOT23 - some of them have actually flipped upside down ; plus we hav

On mixing paste: There could be a lot of hand wringing about the need to minimize solvent evaporation, flux separation, and chemical activity. [True alarmists will throw in oxidation of the alloy.] But I think the real concern is a change in viscosit

Hi Guys, I need some help. I was running prototyping volume previous and my SMT line uses manual printing. Business has picked up and i started to get higher volume 300 to 500 pcs each model. I am running a small firm and have only a small sum of cas

Dittos from A Very Frazzled Man. Money spent on a better process is almost always more advantageous than better inspection. As for manual TH insertion, have you considered a semi-automatic machine like the Contact Systems CS-400? While the "E" serie
