Hi Gani, HASL is normally very good for solderability providing there is a good consistent coating of HASL on the pcb pad. But it is not unusual to have a very thin coating of HASL on the pad and this is poor for solderability. You then have tin/copp

I just swapped from the HASL to Immersion Silver mainly because the board house we use could not maintain consistency in keeping the pads level. I was constantly battling bumps and bad finishes on the pads. They are able to give me a consistent board

Hello Scott, Simply program the side angle cameras as you would for any other device using the downward camera. For instance, solder joint inspection for a PLCC would utilize a basis window, bridge inspection algorithm and individual solder joint i

Hello everyone, Talking to my boss today I was able to determine what we're really looking for in terms of reflow soldering. The company is not looking to do a volume run; we're trying to solder chips for prototype boards, which are currently done w

Hello, I am coming here for some insight and advice. I currently have high volumes (around 40K-50K) PCB's being stuffed at a local stuffing house. We are growing and lately have been putting in more orders with them. The problem is the stuffing qua

I bought an “as is’ Quad IIC package a while back. The machine definitely has issues with the Quadalign Board. The ICs were literally falling off of the board. I am guessing when it was manufactured they did not get the PC board quite hot enough or s

Boots: Here's several methods for guessing at the amount of solder on your connection: * First, 'Down & Dirty' ** Assume that the solder is flat, which is reasonable since it's 'flattened' by the component package ** Assume 100% paste transfer from t

Any and all input will be greatly appreciated. So here it goes. I'm having an issue where the cad I'm getting from customers is referencing pin 1 as the parts placement. This isn't an issue for surface mount, however the aoi machine that we have in

assuming Sn05Pb93.5Ag1.5 Without knowing what you are trying to solder, PTH or SMT, the time might not be that far off. Does that time include stripping, cleaning, plating the leads prior to soldering onto the board?... pre-tinning the board as well
