| What are the factors that go into determining PCB Board temperature requirements for the Wavesolder process? Most of the recipes I've seen call for preheating the PCB to around 230F - 250F. This temp is about 210F - 230F below the typical solder te

Please accept my apologies for being offtopic. I have tried posting on the career center, and our job even appeared at the top of the most recent smtnet email newsletter. Still, we received essentially zero response. I'm hoping maybe a post here mi

Does anyone know of a vendor who manufactures pallets for PCB's. I have a couple of boards where the parts are too close to the edge to allow them to be placed in my Pick & Place equipment (nozzle will hit conveyor rail). I know that pallets are made

This probably won't help much but I find it at least a little interesting. During some experimentation recently I accidently loaded a board into the wave upside down and it had a PLCC 68 package along with other types of components that had only bee

If I were you, I�d be concerned about waving your SO18 too. What is a SO18? Who makes that package? Regardless, it should be a can of corn, if you: * Orient it so that leads on opposite sides of the component see the wave at the same time. * Incre

I have a proto-type PCB with a 48-Pin Fine Pitch TSOP (0.5mm pitch) with a dimension of 19mm L x 11.50mm W x 1.10 Thickness. They are at the bottomside of the PCB and I need to wave solder the board. There are 8 of them at the bottom side. Are they o

Most LCD manuf. specify not to wave or reflow. I believe this is because of the prolonged exposure to the preheat temp. However, about three years ago, we were running about 350/wk of a 40P DIP LCD through the wave with no fallout. It did stress t

Mikeal�s approach is one of the more cautious ones. IPC/JEDEC J-STD-033 clause 8.6 talks about 200�C body-temperature not to be exceeded and how it�s best measured. If you go for that method and you made sure that in your wavesoldering (that�s what
