Watch out for the large board trick. You have to turn the board 90 degrees to run it.

Let me explain. At 125 degrees C, the oven is above the boiling point of water. It will be vaporized and eventually be vented from the oven. However at temperatures of 90 degrees c and lower the relative humidity becomes an issue. For the life of me,

All, What method does everyone use for measuring the heat on the topside of the board in a Wave- we are currently using temp stickers. If the Flux is activated at between 110-120 degrees Celcius does this mean that the topside should read around 90

I'd be leery curing the E-30cl Material at temps above 90 degrees C. (I believe the flashpoint is 93 Degrees C)

We find that baking PCB assemblies at 90 degrees C in a Blue M forced air oven is safe for most all PCB's that we have encountered over the past 12 years. We remove any external plactic hardware that may be attached to the assembly and also like to

Dear Steve. We are EMS company and we are getting wide range of components from our customers. Some of them came in trays, that can withstand up to 75 degree maximum. If someone will not pay attention to this the tray get damaged (if there is some Q

As I told you, some carriers (trays) are limited to 75 degree maximum, and from time to time employees do not pay attention to this. This is one of the reasons. The second reason is that 90 degree still be problematic in a case of rebake more then 3

I rotated my PCB -90 degrees. Now what's the formula to calculate the X-Y Coordinates of my component CAD Data? Thanks,
