I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

I'm repairing SMT for 20 years and I've worked with both machines. From my experience, I always had a bunch of problems with DEK printer and the service is terrible if your not a big one. MPM is more reliable, parts cheaper & service much better. Pro

cn, Currently we have a DEK265GSX a DEK Infinity and a MPM UP3000 printers and previously had MPM Accuflex,MPM UP1500 and MPM AP24s. No advice for the UP3030. We always had to work on all of the MPM printers for one thing or another and every time we

There is a big difference between SMD and SMT. One term denotes a device and the other a process.SMD, or surface mount devices, are electronic resistors that sit on a printed circuit board (PCB).SMT, or surface mount technology, is a method of placin

The problem about covering it with glue (without using solder) is that the components might dislodge by a miniscule amount underneath the glue. So maybe the contact points will disconnect. I'm not sure if this will be a real problem, but if so it wo

Currently trying to get away from using stencil printing. Looking for information on Micro-Dispensing and dot size using a Vermes MDV-3200A micro jet dispenser. I am using a Indium led free solder that has size 6 balls. With a 100 micron dispense hea

There is a new toy I received today: a NeoDen TM-240A automatic desktop pick and place machine! I’ve kept my eyes on this baby for a quite a while, and finally decided to make a purchase last week. The shipping was very fast: DHL from China, a total

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water
