Has anybody adopted the method of stencil printing with the board at a 45 degree angle to the squeegee blade? What are the benefits and drawbacks? I've heard you get better fine pitch results. TX Mark

If an oven is marked with a maximum temperature of 300 degrees C, can it be used for LF? Thanks for your help.

The real question is: Where is your rotation point?

It’s the board origin ( not the panel origin).

Hello, I have one simple question refere to those who use a bit older Pick and Place machines (like 2005). Do you have a problem with placement on 180 degrees rotated boards on multi-panel? When I say problems, I mean shifted placement on X, Y or Th

Have to agree with Steve. PROFILE PROFILE PROFILE It's the ONLY way with lead free. Think about it for a second...a process window about 1/3 the range of SnPb (assuming a 250 degree C max component temp) and you wind up with a fairly small target to

It may be worth mentioning to those that do not have the ability to rotate the PCB, that some folks adjust their aperture design on fine pitch leads by increasing the aperture size for those leads parallel to the X axis, thus allowing consistent volu

The oven's maximum rating isn't really a good indicator as to whether or not it's good for LF. The real question is can the oven get your board up to the liquidous temperature of the lead free solder that you're using. So, an oven that has a max te
