Hello everyone, I am curious what do you think about stencil type and apperture design for better release on small appertures. I have a PCB with bunch of BGAs with small appertures. We tried with Nikel stencil using DEK's special non stick material

I am getting a lot of false calls on our AOI(YTV F1)on low contrast part markings like brown-on-yellow tantalum capacitors and etched oscillators, and on lead banks where the pcb has the part outlined in silkscreen. We are contract and cannot change

It is a very interesting thought. However, teach all positions on the PCB might be challenging if you don't have them in the file. I think it is a smart think for OEMs as they would have all the resources to control their files. For CEM I don't see i

I'm looking into labeling solutions for our PCB's. I've got it narrowed down to the label and the ribbon to match our thermal and cleaning processes, now I'm looking into the best overall industrial style printers. What brand and model thermal prin

Hi I meet problem by PCB with diameter 300cm and thick 6mm i used tin-lead with profile normal, soak time 60-90 sec, Temp peak is 220 degree C, But solder see not good, not shiny. Any body recomend help me to fix this problem for Hard gold playing.

HI, We are facing problem of Dry solder due to QFN Grounding Solder not Drain out in Via hole. also No drain hole on PCBs now we have 15k stock. which is leading to massive Rework. We have Tried by minimizing Ground Square apertures. but no Improvem

When Delta T is measured between components on a PCB, it is recommended that the Delta T between your highest mass and lowest mass component be 4 degrees C or less. Delta T can also be measured between zones on your reflow oven. (Delta T is defined

Hi Bert I had belts made for my conveyors using Habasit material made by Benson's belting here in U.K. They have been running now for 6 years or so and I am very satisfied with them. We are 12K miles away but check out their website at http://www.

Hi Chris. Thanks for the reply. There has been no progress since my post. I was trying to see if I could repair the MVS PCB with IC swaps as it looks a bit cooked in places but if I could find a reasonably priced one I would be interested. I also
