Most places I've seen don't do anything special. But then again most places only have chip components on the bottom of their boards along with some thru-hole. The best way to find out if you are going to delaminate is to talk to the board manufactu

99.70% mounting rates. 4.Make sure your machine can handle the recognition of this components (shape & height) usually height measuring(pick up error) is the biggest problem with resistors. 5.When mounting a real PCB you can have spacings up to 0.3mm

In the following thread, http://www.smtnet.com/electronicsforum/view_message.cfm?message=9584& John Thorup touched on some applications where no-clean fluxes could be a bad idea. I'm looking for some more detailed info. (papers, references, texts

Hi Christopher, To my knowledge, heat seal along will not provide you the desire condition. Currently, we're using vacuum sealer to reseal all MSD restock items. If you have variety of package and constantly need to reseal the MSD parts, I'd like to

You can use a Power Mosfet to drive the light (I am taking for granted it is a DC Voltage the one that turns the light on), the only current a Mosfet demand is only to charge its input capacitance this way you will not damage your board. Configuratio

I second Wolfgang. Welcome, It's good to hear from someone who wants to design something we can build. Another useful resource is the land pattern book from SMT Plus www.smtplus.com 831/438-6116 Also useful are the component mechanicals available (fr

We are looking for a way to cure conductive adhesive. I heard about curing times from 2 hours and more. But I also received information that curing can be done in 10 minutes at 120 C. Of course it also depends from the type of glue. But the question
