You'd more than likely have repairability issues with the Acrylic based one. The acrylic-based finish is alot harder and more brittle versus the silicone. Some of the new silicones, you can just "peel" with your fingernail, while still getting reli

Terry Sorry, I just re-read your question and failed to answer all your questions: Shadowing only applies to coatings that are UV curable. Neither of these are UV curable. You do not want this technology for 3 dimensional assemblies, it is too expe

Solder paste recovery

Electronics Forum | Tue Nov 21 16:58:20 EST 2000 | blnorman

Does anyone have any experience with solder paste recovery? Specifically, partially emptied solder paste tubes. We are currently looking into ways to reduce and potentially eliminate solder paste waste. One of the largest contributors is partially

If you have the individual times for each machine you should be done. Simply find which is your bottle-neck for each day and use that info. You can probably write a seperate program to do this step also, I assume you are viewing all the down time inf

I am tasked to breakdown the causes and to report the best reasons why our everytime we download our CAD Data we need to align or adjust our component alignment. Can anyone help me to identify as I do not have enough experience with SMT equipment. Ju

I have one suggestion why don't you align all parts and take a close look at it if you can find any misaligned component after that. IF SO, that's machine's repeatibility problem.(or mechenical problem-dirty nozzle, wrong pick up and placement height

John , I had some experience of selective solder in a high throughput environment and though the quality of s/s was good , the throughput was not . So if throughput is an issue , forget it . I would go with the hand-solder option , although as has be

There is a variation on the pins that come through on the other side. The pins that are deforming are roughly half the size of those which aren't deformed.There are no witness marks on the pins that are deformed, suggesting that the pins aren't fouli

I love this!!! Two whizzettes with the same information and they spin-off in two different directions. Gad this is great!!! Delamination is a pretty broad topic, but that you have a problem with two suppliers makes me think the delamination is cau
