I need advice for locating 23 Gull wing LED's (all in a straight line) in the x,y, and z axis for a SMT PCB. It is a Hewlett Packard LED (P/N HMLA-QH00-01). The application uses a CCD to detect the position of a ball which floats in a resevior for

In circuit testing is expensive up front because of the fixture cost but the tests are fast. AOI programs can be develpoed in less than a day but take longer to run. If you have good test coverage, in circuit would be a better choice in my opinion-if

I'm trying to determine the best panelization technique, but have been unfruitful in my internet search for more information. I'm trying to determine the advantages and disadvantages of using either V-scoring or tab-routing (break-away tabs), but ha

We are already using ICT on the PCB, which should catch most missing components, also components installed backwards, or the wrong value(to a point - we do RF so we have lots of very small value caps and inductors which can't be measured), and in som

Thank you for your response. I have been told that x-ray strength is finding solder volume and pattern root cause defects, and will catch a high % of them - opens, shorts, insufficient solder, and missing components(shape of solder on pad w/o lead i

Genny, I would like to correct part of the things that you were told. As far as I know, X-Ray tools are not positioned as tools to find solder volume simply because it is not a strong point for them. An X-Ray image is either a projection (2D transm

Hi Randy, From a bare board manufacturers stand point, scoring is probably faster and easier but has limitations. If your boards are square or rectangle scoring will work fine. Once assembled the scored grooves can be sliced apart using what is some

We have 250x340mm panel of PCBs. Stencil for glue would be 0,3mm with about 80 holes mostly for chip components. Our MPM printer at standard set, prints paste on 1 panel at 40-50sec. I need general information if printing glue is faster or slower p

| Looking at the full convection reflow oven market, I see two segments, high mass heater ovens (i.e. Electrovert Omniflow,...), and low mass heater ovens (i.e. Heller,...) | Did some of you guys did some testing on both types and what were your find
