What stencil reduction are you using so the resistors dont bridge??

Re: Dispensing Paste On 20 Pitch Pads

For 20 mil pitch pads, the volume control is more critical in terms of bridging concern. In general, solder paste for dispensing is more prone to slumping due to low metal load and low viscosity. If the volume dispensed is on the high end, or if the

One of our customers' products has a couple of adjacent 0603 packages (one resistor, one cap) that are .010" apart. They are side by side, not end to end. The adjacent pads between the two parts are electrically connected so bridging isn't an issu

Rob: What was driving the uBGA bridging? On your arrays: * I doubt that your supplier would be pleased that you are wave soldering these pups. If you insist, present leads to the wave on opposite sides of the package at the same time. Is this an

Hi Colin, Are you using the 1206 package with 4 elements or one of the higher density smaller packages? With the first type you can get them in both Convex or Concave terminations, with most of the solderability problems associated with using the C

0402 wave soldering

I think so. My customer once assembled resistors 0402 ,by Glue+wave soldering process. But PCB must be printed soldermask bridge between 0402 SMD PADs, otherwise you would encounter short problem. Sorry I don't have any comment for recommended footp

Russ: You�re correct. I should have explained our reasons for preferring concave over convex better. First, we use both also ... we just prefer concave because they: * Don�t bridge any where near as easily. * Self-center better. * Seem to have mor

I am not answering for Techguy2000, but I am chiming in here, I have the same problem. Our resistor packs are ceramic body with no leads, they have a metalized area reminicent of the old castelation leads of year gone by. The lead pitch is 50 mil

Now I have to guess and make a few assumptions. Without looking at the back side of the board my guess is you have some 400-100V diode bridges before the resistor ,zener and the FET . The FET is a 500V 0.85 Rdson NFET. All of this suggests a chopper

Les, Some of the answers to design or stencil aperture/placement machine depend upon what is the current spacing between your components which you didn't specify. Chip components such as 0402's and 0201's typically have very small reductions in pas
