I am looking for some design guidelines (length, width, spacing) for solder thieves which are placed behind trailing pins of wave soldered SOICs. I'd appreciate it if some one could direct me to the appropropriate reference. Also, has any one perform

I would be very grateful if someone could provide me with recent figures (schemes)of 1. pin through hole assembly 2. hybrid circuit 3. surface mount technology. Or could anyone tell me where I can find such information? Thanks a lot. Marjan.

This occurs on only one, two, or three sides at random. But I'll bet that the "good" sides have the same problem ,it's just that the center pins of the array are centered and it gets progressively worse towards each end, just not bad enough to be r

R&D is currently designing a board with smt components on both sides of the board. They are adding a 16 pin IC Gull wing. on the bottom side of the board. I have asked for only caps and resistors to be placed on the bottom side. Is there a recommende

We are having continuous bridging problems with the trailing leads on a 26-pin D-sub through-hole connector. The pitch is 0.100". The connector is going through the wave at approximately a 20 Degree angle. Does anyone have any board layout recommend

Justin, Thanks for the response to my dilemma. For once it's not just me! The parts seem perfectly solderable, but I will try the modification to the profile you suggested. I wonder if the retention clips may be letting loose from the holes they a

Is there any way to implement SMT at home? I want to assemble a prototype board of mine. How can I hand-solder a 208-pin 0.5 mm lead pitch PQFP -- lead-by-lead (the usual way), or side-by-side (partial heating method)? Alas, no SMD rework equipment a

Does any one know of good articles on the DSRS I have never seen a complete article only a couple of paras. I am writting a guide for the SMART Group in Europe which we are selling to raise money for charity just like our latest report on Pin In Hole

Howdy All, Just want to know if solder pre-form really work. Any pit falls? Looking to solder a through hole connector (70 pin) in a 0.062" PCB with 10 zone convection reflow oven. My biggest worry is getting enough wetting on both sides of the b
