You�re correct. This is a messy situation. Do not store components at the bake temperature longer than the time required to dry out the units for use in the reflow. Long storage times at elevated temperatures can cause soldering problems and the

Hello! We want to try Lead Free paste Sn42/Bi58. Can we use this paste with Lead fihish such as HASL. I am worry about low melting temperature of 138C.

I used a Blue M batch oven quite a bit to cure in works great. All you have to do is get the board up to cure temperature, 150C normally and your all set. It will probably be in there longer than the time required but at that low temperature it shoul

Assuming that your components and PCB's have good solerderabillty and are stored in an air conditioned environment and kept free of contaminants then your problem sounds as though there is insufficient wetting of the component leads due to low temper

You never mentioned the size of the board? You will find a vast array of pre-heaters with a range of prices. I could reccoment a few products based on the size of the board in question. The solder iron staying at temperature while not being used is a

1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? 2. What is the �Low- Temperature Phase� in any solder paste alloy? 3.W

We have an old (dinosaur, 1992 vintage) heller 988 that we use for shrinking heat shrink, curing, low temperature stuff. We need another similar oven for expanded production. Essentially any reliable, running, non-lead-free three four or five zone ov

I'll answer the easy part. If you put low temperature trays in the oven at 120C, they will warp and partially melt. I have seen it more often with reels of LEDs. Someone is told to bake them before use so the put them in the batch oven and the next

It doesn't appear to be a proprietary mix. Maybe it's 'neither Alpha Metals nor Kester WILL [want to] supply it.' It's interesting. A lot of the discussion of a solder replacement for 63/37 has centered on high temperature alloys. In real life,
