moisture in vga chips

woodford · 09-13-2011, 01:10 PM

can anyone recommend a method to get rid of moisture in new vga chips.i replaced a chip on a dell xps today and it popcorned when the temp got up to solder melt point.

i am aware that baking in a oven will do the job but i dont know how long or at what temp.also is there a oven i could purchase that is made specifically for this job or is it just a case of using the preheat on a reflow machine

thanks.

Page 4 gives some good recommendations.

The general idea is to get the moisture out slowly.

Most reliable way to be sure is keep them in dehumidifier cabinet for a week or two,
this will do the trick.
