I have routed many stencils out of very thin (.005") FR4 unclad pcb material. Unfortunately, I can't get any more (Isola Laminates doesn't seem to have any demand for it from real customers any more), so I'm going to switch to Kapton film, either .0075" or .010" thick.
I've bought syringes of paste from FCT Assembly, but have more recently figured out how to fill my own syringes from the more common 500g jars of paste. I take one syringe, preferably a little smaller OD than the ID of my desired dispensing syringe, and cut off the bottom. I press the open bottom syringe into the jar of paste, then push the "slug" of paste into the dispensing syringe. With a reasonably small gauge blunt needle you can put paste on small one-off boards quicker than you can make a stencil. For repeat boards, or ones with finer pitch parts, the stencil is nice. -- Ralph ________________________________________ From: Marshland Engineering [marshl...@marshland.co.nz] Sent: Sunday, September 22, 2013 5:49 PM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] advice needed I'm going through the same process at the moment. I have sent my files to Seeed. My boards are small. 40x40 mm My small reflow oven is on its way at present. Seeed apparently also make stencils, however I haven't priced them as yet. I've been looking at solder paste and syringes and there is a myriad of them around. Can anyone recommend a good product ? I have a A3 HP plotter and was wondering if this be adapted to use a knife for making plastic stencils ? The other option was an 1W eBay Laser fitted to the plotter to cut the plastic. I'm using 1206's so nothing IS too small.
