I�m surprised how un professional the so-called experts can be. After all we all had our start sometime and if you can never remember asking a un qualified question in your entire career then you probably have a bad memory. This is an open forum for

we have a HSP 4796, and have had placement issues with 0402's. If you can rule out global correction, rev'ed boards and a loose nest or a lack of support under the board. Look at placement before reflow. If alignment problems are present before oven

I agree w/ JB; the package height definition is crucial. I have had problems w/ this in the past, and found that a resistor height was being used as a universal passive height for the capacitor in question. Properly defining the height fixed the pro

We also have 4796's and 4791's and have had the same issues with 0402 parts.. All the suggestions listed in the last post will help quite a bit. We found our biggest problem was the board supports due to the operators using the wrong type of pins ,

Component shelf life depends on: * Solderability protection type. * Quality of process and materials used in applying solderability protection. * Duration of time from when the solderability protection was applied. * Packaging used in component stor

I use conformal coating DYMAX #984-LVUF and I don't know if it's a problem of viscosity but 0805 components are not covered properly. We use a dispensor to applied it and we cured it by UV. Even if I apply a thicker layer, the coating seems to have

Hi Dave, Was planning on skipping the paste step & screen printing the adhesive straight onto the pad, then placing the component into the glue & curing. (Board has LEDs only) Regarding the lead-free HASL issue - not entirely sure on the board man

Hi C.B, I have been doing some repairs on a Quad 1000 and I am getting to know it better that I want to. My comapny is located in San Jose, CA and I can offer you on site support if you are in the area. I also had an operator "update" the configura

Actually, in thinking about what someone else had posted - I'm willing to bet that it's not that I'm losing parts and the nozzle is actually touching the paste, but more that since the nozzle peeks over the sides of the component slightly, especially
