| Hi folks, | | I am looking for inputs on a long-standing problem encountered in our shop: Bottom-side parts (passives) falling off in the Wave...where the only remnants of the part is a flattened glue dot of proper diameter and volume, and somet

Hi All, I work with CNC Routers . I use full perimeter routing of double sided populated panels, in a high volume/ mix application environment. We chose stand alone routing machines for our facility . I'm interested in your input for better ideas

| We are considering adding surface mount components to a board we currently produce. The board is made from CEM-1. Has anyone had any problems with surface mounting to this material? We use a glue/place/cure process. | | Thanks in advance, | |

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

We just use scrap PCBs for Oven carriers. You could probably contact your board house and as for just sheets of FR4 to use. I've also used a binder clip at each corner to lift a board off of the mesh belt in a pinch.

A couple of caveats; The FR4 will degrade with successive reflows and will eventually need to be replaced. Not a big deal for low volume, but something to be aware of. The bigger concern is that a sheet of .125" large enough to position your assembl

Problem is I don't have a mesh belt (lesson learned). Our conveyor is pins. If I laid some scrap pcb's spanning the conveyor pins on the long dimension of the board, I'm confident it would sag. We get a bit of sag today in our 1.6mm thick boards whi
