From the picture you present, it is a pin in paste part with pin length 2.2mm (a good length for 1.6mm PCB thickness), and seems the pin tilted and touch on PCB surface, thus causes up-part. Sorry I cannot image pin tilted not before placement but i

Well everything Graham said with some additional points.. You mention manual printing but very little about your stencil or setup. Everything you have said indicates a very limited budget has been expended, however what you have is an extreme exampl

I don't have our DEK printer part numbers memorized, In general we have a older machine running NT4.0 . It has 2Di inspection but we never use it because you can only inspect/setup 1 camera shot at once, making for very long programming. Our newer D

We've had our My500 for about four months now, and couldn't be happier. We are a super-high-mix, super-low-volume shop, and the flexibility provided by the 500 over stencils is stunning. So, you buy 5-10 stencils a week? That's 260-520 stencils a

Hello all, I read about Steve's headache a few articles back and I'm really interested by his tip. However, I'm still wondering why square apertures release solder paste better than round ones. For the same volume of paste, the surface area of th
