Wow! It really works. I used Sprite instead of the hussle of melting suger. I did not use Coke as it leave behind a black stain. Now, I need to convince the facility people it will not attract ants. Or maybe it will be process inherant that ants wil

Judy: There's no spec. I think you need to define a minimum requirement (1 tack per inch is OK) for your purposes. Check the guidelines on http://www.circuitnet.com/ for more back ground. We just drag the tacking iron along the wire. It's faster

You have may have already checked this but verify stencil design (aspect ratio) and make sure you are using the correct paste (mesh size) Also look at perint pressure. up to 2 lbs per inch of blade used. You may also want to use a slow break away whe

You want to use a rubber squeegee with as high as a durometer as you can get away with, order two or three sets of blades starting with the softest and then progress up the the hardest, the reasoning behind this is the softer squeegees will wear out

Hello We are currently getting Proto's of legacy product built up in Europe. Our current supplier uses a spec of 14 micrograms or less of sodium chloride per square inch as measured on a omega meter. THe product is Industrial and I am not sure do we

I need to place one type of part (0.080x0.017x0.010 inches) on a flat wire with an accuracy of about +/-0.010 in any direction. Volumes to be about 500 to 1000 per day. Are there any relatively small pick and place machines available?

Look at your paste specs, they give you recommended starting points relating to speed and pressure. Dave F is right, it is usually about 1 pound per linear inch of squeegee length. Speed for finepitch printing should be started at about 1in/sec. T

VIP 98, I believe that's a 7 zone if I can remember 6 years ago. Try 150, 165, 200, 235, 235 and 235 (top and bottom temps) with a belt speed of 35 inches per minute. This should get you in the ball park depending on the size of your board.

Force is definetely necessary. It really doesn't have much to do with board thinckness, if everything is programmed correctly. It is just the downward pressure applied to the stencil during printing. You are supposed to adjust this depending on yo

Hi, I am using a 7 zone Conceptronics oven and Indium 3.1 lead free clean paste. Our profile is as follows, 130 140 150 180 200 240 260 with a belt speed of 36 inches per minute. I dont know if that will help you out though...
