Is anyone aware of a good, basic Electronics assembly course? There is a manufacturing project leader in my company that needs to get some good exposure ... quickly. He is particularly interested in design for manufacturing.

We are trying to eliminate/minimize the baking process for high lead-count ICs. We would like to reseal packages containing these parts to minimize exposure to humidity. Anyone have or know of a way to reseal or vacuum pack parts? Any suggested eq

Praveen, Once you find out the MS level of your components, you will need to track the exposure time from when the parts are initially removed from their dry bags, through test, programming, taping, and during subsequent dry storage and use of thes

Hi mates, Yes, the lighter mass is a valid reasoning. in addition to the "lighter (mass) than thou" point of view, 1) the first reason for mounting active Parts (eg. IC, QFP, LGA...) is to minimize the temperature exposure of the Parts to a single

Syringes seem to keep the paste fresher longer since there is less exposure to air than a jar. It is also nice to be able to just squeeze the trigger on a gun instead of using a spatula in my opinion. Russ

Hi Chrissie, This might be old news to you but I just wanted to make sure that you are aware of all the implications of BGA rework relative to the control of moisture-sensitive components. For example, you need to keep track of the total exposure t

Hi What is your reflow profile ? Try to limit exposure at parts with visible leaching to around 30 to 40 secs at around 235 to 240 deg T

the puspose of solder mask is to prevent exposure of cu tracks to atmosphere. the lesser thickness can effect the performance of board but it only depends on its application. if you are making telecom board then its not good to use the board.

I have already posted a want ad on this site for feeders, but thought this forum may get a little more exposure. Anyway, I need to purchase some used 8+2 feeders for Universal 4796 both Paper and Embossed. Any help-leads would be great. Thanks,

Thanks for the info. I have looked at an EVA mesh that will pass esd test as well as exposure to w/s flux and hot water. Stainless is great but the the softer material is what I want. I want to get samples of the thermoplastics from Mcmaster. Thanks
