2010年12月2日 · So 30 mins gives enough paste to do a whole board saving me at least 2 hours of arduous smd wire-soldering work pin by pin. That's 1.5hrs saved, subtract another 15 min for placing parts & solder paste stenciling. Still 1.25hrs saved per board. Plus no solder wasted and better fillets all around, with no heat damage to components or traces.

2016年7月27日 · In order to gauge the degradation, it is best to put a small amount of paste on a non-wettable substrate, like a piece of ceramic. Reflow the paste and see how well it coalesces. If coalescence is good, the solder paste will reflow into a ball, surrounded by a flux pool that is relatively free of uncoalesced solder particles.

2015年12月16日 · Most of the needles I use for adhesives and such are in the 19 to 22 gauge range. I still use fine solder (0.015") for hand soldering and have not used solder paste, because it has such a short shelf life. For applying small dots of whatever or for holding parts, I use "tooth picks" made of music wire. I simply deburr and slightly round the cut ...

2011年12月11日 · It doesn't look like soldering paste and when I went looking, ebay showed these results: **broken link removed** AND called it solder flux paste. Flux helps clean surfaces and helps parts stick. It is usually cored inside of some wire solders. It's used in surface mount technology primarily for large parts like a USB connector when using solder ...

2009年7月21日 · Yeah you can get mains powered fine tip soldering irons with an adjustable electronic temp controller in the plastic handle, I bought a couple for about $18 USD each, perfect to chuck in toolboxes etc for times when you need to fix something for a friend.

2018年1月21日 · Looking at using a 44 pin smd to progress with my latest project. Have board designed using a 40 pin dip but way to big for my project so having never re-flowed smd using a skillet am now considering. One issue was the shelf life and need of a stencil, Stencil costs $16 soldering paste that...

2011年11月2日 · No, absolutely not. For either soldering or desoldering SMD's the board needs to be pre-heated. The only difference between desoldering and and a reflow soldering profile is any chips you don't want to be desoldered need to be shielded from the peak flow that brings the solder up into the fluid range, what are you using for masking tape?

2010年12月8日 · Use a rag to smear a light coating onto the wire, I have used this paste method successfully many times on marine applications when other methods have failed. Its important to remove any residual paste from the work piece after soldering, a wipe with a rag moistened with methylated spirit is OK.

2009年4月7日 · Then apply a little bit of paste flux to the leads and apply it to the PCB pads. Then go back in with the soldering iron and heat up each leg till the solder re-melts. You have to use a paste flux or you'll either get a bad solder joint or end …

2022年1月21日 · So i got myself a Electric soldering iron kit 30w, some solder 50/50 and some soldering paste. And try to solder the shorter leg. I managed to do so, but i am worried that it wont last very long. I was wondering if some of you guys could help me figure it out which component is the one pointed by the green arrow.
