Hello Nick I'm not aware of any published 1:1 footprints. couple of options: Topline dummy show and tell display cards. $$ I believe. Since there aren't that many different pitches, get one of each and glue those puppies to a card. Could be new, dea

Nick, Like John says, it will only be a short time and you will "just know". In the meantime you might want to try - 1. All the placement machine manufacturers have show pcbs for the exhibitions, many of these show pitch and package types on the silk

Travis: Several points: * When we converted artwork (back in the Jurassic Period), we used a huge digitizer pad and the original artwork. * While your Rube Goldbergian (http://www.rubegoldberg.com/gallery.htm ) arm encoder thing sounds fascinating

Walter, First of all, if I recall correctly you should not need a 6" leader for starting a reel on a Mydata. Mydata's have a reel leader extension attachment with a V hook at the end so you can avoid this need for a long leader. You should be able t

Craig, I'd be really hesitant in pursuing this method for a TQFP. Remember, most SMD's are rated for a maximum rising slope of around 4C/Sec. Immersing a fragile TQFP in a hot wave of molten solder will probably exceed this ramp up rate. Besides thi

Hey all, My brother is a tech at TI. He is running tests on bump dies. The question is if he heats up a die (actual waffer) with out disrupting the solder can he still use the solder. Will the solder lose its integrity? Keep in mind that these

50% of cost, bin it. If viable, spend no more than that time to fix. Then concess or use as is. 3) Components are more tricky. Can they be returned to supplier if deemed to be faulty? (proof?). Is/was there an in-house handling problem ? Have design

There is a wide range of price points and configurations for such equipment. RFA (Read the Fine Archives) and contact the suppliers (supplier lists are in SMTnet and "SMT" & "Circuits Assembly" etc magazines) and get back to us with specific question

I think you could look at the phenomena in two dimensions. Many of the sub-contractors in Asia are focus on low price-less demanding products. They hire operators to visually inspect the boards and sometime there is no inspection at all. On one ha
