You can achieve a wide range of dot heights when stencil printing by using a polyimide stencil along with a .040 snapoff. Loctite has a system for this that they call Varidot, by varying the size of the apertures in combination with the .040 snapoff

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

0.65mm pitch QFP. I believe that this is the borderline for Fine Pitch. Will I have a good paste release with Chem-etch matched with a rubber squeegee? I'm planning of a 15% reduction on the Width and no reduction on the length. Any feedback whether

Hi, You don't need X-ray and all that crap. I would get an old MYDATA TP9 or something like that, and a manual stencil printer and a batch oven or a small inline oven. Should do the trick and be very low cost. Should be simple to use as well. Tha

You should ask yourself a bunch of questions before you consider going down this path. The first being where are the bottlenecks in your existing line and is there anything you can do to eliminate or decrease there bottleneckness (made up word). I

Subtle spamvertising there. Lower Cost small machine brands worth looking at are probably: Mechatronic Intelligent Drives (UK only?) TWS Autotronik or their Manncorp branded models in the USA Fritsch Innotech Heeb (a virtually invisible market share

You are looking for a complete SMT assembly line plus possible X-Ray inspection and rework equipment. The 3 components of the SMT line are stencil printer, pick-n-place machine and reflow oven. How small are your components? 0603? 0402? What is the

Hello everyone, I work for a company that, up until now, has done everything using through-hole components. This has been fine for years, but we have been pushed into the world of surface mount manufacturing by a new product that is far cheaper and

First, let me say what I always say: a good chem-etched stencil will print fine pitch. Chem-etch brings trap to the side walls because its a physical by-product of the process. Because they are less expensive you can add electropolish and still save
