AI Thread Summary
Wave and reflow soldering methods rely on the melting and reflowing of solder to create electrical connections between component leads and printed circuit boards (PCBs). Key principles include capillary forces and surface minimization, which facilitate the wetting of the metal by solder. The heated flux plays a crucial role in enhancing wetting properties. Understanding these principles is essential for optimizing soldering processes. Overall, the discussion emphasizes the need for clarity on the underlying scientific principles rather than just procedural knowledge.

guys I've beng searching internet long time to find the principle used behind wave and reflow soldering methods,but all i get is about its procedure.

can anyone tell me what is the principles behind these two methods
thanks

The metal solder melts / reflows and forms an electrical connection between the components' leads and the PCB?

If you really, really, want a principle, maybe capillary forces and/or surface minimization involved in the wetting of the metal by the solder (or maybe, the heated flux allowing for wetting). I'm not a materials chemist.
 
I'm not sure,question was "what is the principle used in following soldering methods?"
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
