I am working on 0201 development for my company in the UK, and I am planning a rather extensive DOE for my reflow oven profile. I am planning on studying various ramp rates, soak times, times above liquidus, peak temps, etc... My biggest concern

Hi mate, AOI seems great for : 1) missing 2) wrong parts 3) wrong orientation 4) x-y axis misalignment 5) upside down placement 6) etc.....? AOI shucks for : 7) unsolder (joint) defect 8) tombstone / tilt My guys are evaluating AOI m/c, for substi

In my experience AOI's are good for checking machine setup I.E. first piece inspection. After that the only things they will typically catch are wrong parts, reversed parts, missing parts, and tombstones. I would however suggest getting an AOI with a

In a perfect world, the machines would be maint."guys" for the automation machines. Think "closed loop" system. Anyway, getting back to our reality job, we are still game for automation to improve thru'put, quality, reduce problems. The focus here

This problem exists at a very low level but happens on all our discrete components, all our products and in two plants. Between the PCB land and the component termination there is a barrier of flux residue, this actually lifts the component slightly

why you need to verify every day? We do it only if machine start missing a lot, and using board with banch of misalignment's, tombstones and other problems.

You could spend 30 mins inspecting a modestly complex board manually using a magnifier/scope and still miss things. Humans get distracted, bored and tired. It is also difficult or impossible to visually inspect some faults like mild tombstones or qu

I�m interested in the F1 model, due to the possibility of this system to be configured with 1 top camera and 4 side. We are manufacturing 0402 and 0.4mm fine pitch Lead Free, and our PCB�s quality is not very good. With just one camera are you able t
