No question that metal retains a lot of heat (slow to heat up and slow to cool down). But again in a batch oven, it mainly boils down to the heater. I know, until you see proof you are skeptical. I think by posting a url to product specs will

Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven

Q1a. If the thickness of the silver is too much (how is too much??), A1a. We have heard stories of using Ag2 to limit silver [or gold] dissolution, but have never seen formal studies to demonstrate that idea. First, exclude the use of silver plate

The ramp sets the stage for flux activation, and if ramping in a linear fashion, burning off some of the volatiles, but yet preserving the activators. The ramp is also intended to preheat the SMDs to prevent thermal shock. Most solder paste data sh

The initial cost of the battery is similar to saying the size of an iceberg is measured only by what shows above the waterline. There is a lot more to it than at first blush. The ECD Power Pack costs $245, but provides over 3500 hours of profiling.

Hi Craig: I agree with muse. The problems almost always will show up later on duringg life cycles in terms of reliability problems. While the solder joints may look acceptable right after production there is no guarantee of meeting the reliability r

Technically speaking, most likely yes it will work, unless possibly it is a BGA. There are issues surrounding BGA's. Here are some of the general issues: On any type of component, if the Pbfree solder you are using contains bismuth, then the Pb in

Well, my first thought is that you need to consider lead-free rework. Depending on the alloy, some stations may not be able to reach the correct temperature. The best stations I have seen have a prism & shows both the pads and the BGA on a single v

I would suggest you do the following: get a sample / scrap board that you will be reflowing, attach thermocouples at various locations on the board, send the board to APS or whomever. Ask them to run a profile based on your solder pastes manufactur

Hi, Expert, Currently, I'm facing a very critical problem on my HAL leadfree finishing PCBs at my customer end. We run the HAL leadfree (Tin, cu and ni) board by using HAL leadfree machine (temperature about 270 deg.C) and go for normal water post c
