| While inspecting incoming PCBs we detected around all plated-through-holes (only there and all in the same place) some halfmoonshaped light rings that match obviously only with the pink ring symptom shown in the IPC-A-600 chapter 2.5.2.. That would

We have recently had problems with bare boards coming in too thick. I would like to know how to properly specify the minimum and maximum thickness using the 13949F and IPC 4101 specs. (We currently use "MATERIAL: GFN 0620 C1/C1 A2A per MIL - P - 1394

We agree with Rob. It looks like either kiss is blowing the paste around. It could be: * Nozzle id too large. * Kiss is occuring after the head has moved from the component. 0408%20MS%2001.jpg - Paste is not missing on the bottom-center pads. It is

I've been using an Omrom machine for over 5 years now. I have mixed feelings about it. It has paid for itself many times over, but it needs constant tweaking. Constant tweaking is something I believe all AOI machines need, but the way our system wo

We currently use a YesTech M1 system and we are looking to buy another. Two important areas to look at when pursuing AOI equipment: 1) Camera resolution 2) Light sources Depending on your needs, camera resolution can be important depending on the si

Ive used a Mirtec machine for 3 years MV3L with side angle inspection. Mirtec has some issues documentation, and repair plus. But there machine is impressive and the AOI software is good. We can find about 90-99.99% of all errors using just the 5

A reading of the pictures is: A1: Looks like pad [B1] is smaller than the other pads. It�s weird that the pads are such different colors. A2: Looks like pad [B1] is smaller than the other pads. Solder mask opening [B1] is misregistered and seems s

RS, It seems you've been doing your homework. However, the real question is what do you need to do with AOI? 1) What is your minimum cycle time? This would help you to determine the speed you need and whether "scan on the fly" is warranted. Also,
