These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

A lot of your success with waving SMT components is dependent upon design and what type of wave forms you use. Without knowing how the board is laid out or what type of wave you have it is pretty difficult to determine what the yield differences wil

It is pretty hard to wave solder fine pitch parts bad enought with 0.5mm let alone 0.4mm It can be done but need N2 inert wave soldering & need layout design to accommodate this... Iy it is a QFP need to run part 45 deg into wave and if possible in

Good Morning Everyone, We have a customer that produces RF based assemblies. We are building several board types for them, all of which have an "RF" area of the PCB. This RF area does not have any mask to define pads. There are also several issues w

Istv�n: Given a choice, I�d run second side PLCC44s at 90� to the wave. As far as thieves are concerned, I�d have two, mirror images of each other. Unlike most, these thieves are not connected to pads. They are out-side of the last pad on the sid

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on
