| Hello, | I am looking for suggestions for cleaning pcb's after the routing (fabrication) process. Keep in mind that these pcb do not have components intalled on them yet. | We have considered pre-drilling the routing plunge points, but cost and ca

Hi, My company is currently experiencing a high feild failure rate on a 100nF chip ceramic that we use in various applications across our product range. One of them being de-coupling which means we use millions of this device every month. The failu

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

Do the math first. 10,000 boards a month means 440 boards a day (roughly, and not including weekends). Do you plan 2 shifts or only one? If one, you need to produce a board about every minute if you work an 8 hour shift. If all 110 parts are on on

PCB > Origin > Origin 0 4 Teach the corner of the pcb at the mechanical stop. This data is from the machine origin. For a unit with a teach camera it will probably be around -25x, 95y. For a beam sensor around 70x, 28y. This is for a right to left

For the most part there would not be a lot of change over. There are two primary boards at this time that would be run on the line that also use common components. At this point all but a couple of the pick and place machines we have looked at have t

I'm fairly new to SMT, but highly experienced in other materials engineering areas. But have found the definitions/specifications for pastes to be both confusing and inadequate. I have often see graphical representations of the "desired" thermal pro
