If you have room try putting a small piece of tape on the bottom of the stencil right next the aperture that is giving you the problem. The added height of the tape (Kapton tape is usually about 3 mils thick) will likely give you a heavy enough depo

Thank you for this information. I will try this. Infact i am already working on this type of idea. In the mean time, I did try the traditional HAL finish on PCB since it can reflect the light to some extent. I am also trying lacquers peters white s/

Ken, We're talking pennies. Even though the cost of a reel would be cheaper than trying to account for lost components I have to come close in figuring this attrition amount. Reason being is to try and prevent unplanned shortages. I am in constant

Take a solder iron with some wire solder and attempt to tin the leads of the component. Look under magnifier or microscope. Did they wet? If not try fluxing them with liquid flux and then soldering again. Did they wet? If they did not then you may wa

Hi, We only use alcohol for cleaning stencil but it gives us best result even with no clean solder paste. We are using Branson.Furthermore, we have fine pitch components.Try cleaning the tank maybe there are solder accomolation in the tank or try in

Per Bob Willis, the UK based guru of all things lead-free: "The only thing those swabs do effectively is lighten your wallet." Really, they don't work reliably at all. You are better off trying to do it by visual inspection. I've tried out an XRF

Hi, I think I'll try to do it on my own. There's a company here that does this stuff, called Car-San, but the want to charge me $100 Canadian to do one chip on one board. Min order, I guess. I think they were just trying to shoe me away. So, I bo

HI, thanx for opinion ;) tried Searching but obviously did some mistake in 'words' and got 0 results ;p I've already tried high temp solder - but it's damn difficult to solder TC to the component... I'll try aluminium then...but from what I rememb

Have you tried to run the same process but with diffrent solder paste manufacturer.? This give you information whether paste is ok. Try also print paste on the bare board and run through reflow oven. Check 2-3 boards. Is it the same places where i

Not to squash anybody's ingenuity, but most of the problems that you're trying to solve have been solved, and fine tuned, over the last 30 years of SMT. (Surface Mount Technology) I'm all for reinventing the wheel, but I suggest taking some time to
