I'm needing some info in regards to the usage of a Wave Rider. What is it basically used for? I have to implement one into our process and I'm trying to find out what some others use it for. This is going to take the place of our Slim Kic and glass p

Donnie: Chrys wrote two excellent commentaries of the wave rider that are in the SMTnet archives. Yano the key thing for me in this? If you can't figure the usefulness of the wave rider, I imagine you either have: 1 Developed alternate approaches

I need some input to clear up some confusion I have with regards to what standard I should be using for workmanship on the pcb assemblies we produce. Should I be using the IPC 610b or the ANSI-J-STD-001B? What is the norm for the industry or is the

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

Thanks, Dave appreciate the info. One of my trains of thought was leading to the convex because I thought that having the "bump" would allow for easier wave soldering? I did look at some data we had and did find you to be correct, the concave hav

Angela Do you see this problem on other .5mm pitch devices or is it only on the QFP? Check placement height, too low or to high can cause you problems Pad co-planarity, are your boards HASL? Is your board sagging during placement(board supports) An
