Hi All, We are producing a veriety of RF related PCBAs in which we see Unsolder/Mislaigned on a regular basis. In these baords usually one of the pad is connected to a signal trace and the other pad is connected to very huge ground plane. This gro

Dear SMTNetters: What are some favorite techniques for getting all of the solder from a plated throughhole on a heavy ground plane area? We are using a SAC 405 alloy. Regards BWET

Your problem is at your board house with the finish. There is not enough tin deposited on the ground plane. Could be the current density too low on the ground plane. If electroless they just didn't process these correctly. What is the finish suppose

on the front end in design, minimize the pth connections to ground planes. this takes alot of work by the pcb designer and the approval of the design engineer. connect maximum of 4 ground planes to pth, minimum 1 plane. use spoked connections. ev

I think Steve is on to it. The wire is not getting hot enough to wet. Either the solderer is attempting to solder too quickly, or the PTH is connected to a ground plane. The solder sticking up through the hole leads me to think it's connected to a

tjc, Is this pin connected to a heavy conductor or ground plane? Chris

Most likely ground plane stealing your heat. Increase dwell slightly if you can.

When you sat design problem, is it a because there is a ground plane causing a thermal problem?

Windowpane your ground planes, this will prevent a lot of voiding.

CJ- If I am not mistaken the Zephytronics machines have a money back guarantee if not satisfied. We have boards with huge ground planes and the air bath is the only rework that can do this. We also have found heat guns get hot enough but the heat is
