Hi Stephen, The component falling off is the component that had glue. the component witout glue is being covered by masking during wave. What is the meaning by populated the part and cure it? is it run with solder paste profile or glue profile or yo

When conformal coating a PCB, when it comes to components such as alum caps, if no keep-out specified for SMT, would you recommend coating the entire component, or would you only coat the bottom portion (where conductors/leads are present) Moreover,

Hi Guys, (Note: We are not talking about bill-board RES/CAP, we are talking about Z-axis slant/tilted RES/CAP with respect to the PCB pad Z-axis plane). 1) We ref through the IPC-A-610C specification "bible", and can not find a "chapter/verse" tha

I have been researching older lower cost used Pick and Place machines and so far I am leaning towards the Quad IV C. There seems to be a fair amount of these units around and I have heard some pretty good things about them on some of the past posts.

I have been told that is is possible to reflow solder through hole components. Can anyone confirm this is being done reliably? If so, what are the required equipment, steps and processes? What is the reliability of the solder joints? Is this a genera

Strange, the OP said they don't want to use PDF because all the manual work to get the data out of PDF and into what ever system they are using... The data books from Practical are in PDF, so no help there. Unfortunately, I am not aware of any other

I've seen the catalog of Practical and it really can be used to extract the necessary parameters (like every catalog for SMD parts). But maybe the thing I'm seaching for does not exist. So I may create it. Thanks and good luck.

Bad cleaning practice is suspect. It is believed that W.S. flux was used to solder adjacent components and then hand cleaned. This is not definite but it is pretty certain.

How many mils the gap between the terminal and pad? Your practice is for technology SMT-4? What is problem with glue cure? is it due to the reflow profile? how long the glue can be keep in room temperature with humidity 40-60?
