Water-soluble flux provides good soldering results because they have good flux activity. They have good wetting action (ability to remove oxides and prepare a clean surface for soldering). However, they may be too aggressive, calling for extra precaution during cleaning of the PCB Assemblies to ...
Tape inspection for post-packaging: A complete inspection of appearance is conducted after packaging (as shown in Figure 5 ). The slightly upturned pin in the tape is difficult to be removed by visual inspection. Thus it is shipped to the customers. Solution: Modify the standard on the proje...

How to calculate directional conductive heat flux through solid body? #1 barisp New Member barisp Join Date: Sep 2020 Posts: 1 Rep Power:0 Hi, I'm trying to solve a conjugated heat transfer problem that consists a heat sink getting heat from its bottom surface through a CPU and ...
“Let them know that you are sorry and that the shortfall was not intentional. Create a plan with them for some kind of resolution. Try to find ways to help them with the resources that you do have,” Rebell said. Lending money to a friend or relative can be risky, so it's best ...
What is the electric flux through (a) surface 1 (b) surface 2 ? In designing machinery, would we prefer to use materials with a larger or smaller coefficient of friction? Explain your reasoning. Explain how and why the velocity of an object changes when it falls in a viscous fluid. ...
be corrosive or cause a high-resistance short between pins (not good!). You are technically supposed to use hot, de-ionized water for "water soluble" flux, but we can get away with some isopropyl (rubbing) alcohol. You can find rubbing alcohol at just about any pharmacy or grocery store...
The flaw detection method for the transverse crack at the bottom of the weld rail is a "crescent-shaped" damage (perpendicular to the bottom of the rail, constituting a right-angle reflection between the crack and the bottom surface of the rail): the probe K1 or the rail flaw detector 37...

That unbroken surface, however, is also super-easy to clean. As you might expect with any stove swap, it takes some time to adjust muscle memory for one range’s output for another’s, which can be a issue for particularly temperature-sensitive recipes. The embedded electronics in an ...
