There are several things that can be done to increase throughput on you screen printer, including the panelization of your bords as Steve & Hussman has pointed out. However that's of limited use if you have plenty of stock that is not panelized. That

I do think that the designer goofed, and used too large vias. I believe he only used on size via on the entire board, regardless of whether it was in a pad, or out on the board. I have seen vias in pad work, though. From a manufacturing standpoint

Hello, I would like to ask for opinion on an epoxy application. We apply RTV to bond and secure 2 electronic devices on a PCB. But after noticing the RTV bond breaking off during vibration test, our customer has specs in a 5min 2-part epoxy (made

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe

I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,

You can spend a couple grand on a manual screen printer, or do what I did back in the day: place the board on the work bench and lay the stencil on the board. If you can hold it steady enough you can use a putty knife to apply your paste. For the s

I run a prototype/small-run shop, so I'll include some recommendations too: 1) Don't buy a machine for just what you are doing today. Once you get into this field you will find demand to do more. 2) Don't scrimp on the stencil & machine. You will spe

$200 is iffy, even for a used, reconditioned unit. I got an aged Olympus for about that some years ago, but had to make my own stand. There is a Chinese-made stereo microscope (no zoom) that is absolutely worthless for inspection, because the "thro
