we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,

We are currently experiencing a high rate of false calls on our 0402 chips. Resistors for the most part. Has anybody out there found a setting where this false calls are minimized? We are using top red light, pattern inspection,color inspection ( wh

Help! Does anyone know how to get a Camolot Gem II machine to put down dots for 0402 placement? I have been working with Electrovert Tech's that say their machine WILL place dots for 0402's. I have reduce the speed of the pumps to half the speed,

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

The 740 and 760 basically have the same specs as far as component ranges: 0402-50mm components. The 760 is a bit more accurate and the vision system is better. The 740 was designed when BGA weren't really around and so it can barely vision center b

hello; When we are doing component land pattern design , one thing will always be in our mind; that is the basic criteria or common land pattern design guideline for reflow and flow solder assemblies. For basic fomula in calculating resistors are:

I think he meant stencils where the print pattern is front, left, or right justified on the stencil itself as opposed to being centerred. Is that what you meant. It can be done on DEK printers, but it has been several years that I worked with an MP
