We are doing hand soldering for the 'BATTERY LITHIUM COIN CELL 3V CR 2032 but now we want do the soldering through wave soldering process ,for avoiding the shortckt only one pin will get solder through wave process and other pin will be soldered manu

I'm looking for some SMD shims or something to solve this problem. We have a coin cell on a PCB and the side that contacts the PCB also has traces under the cell that don't connect to the cell. So I'm after some small dots of something suitable for

To be honest, I have never had success wave soldering or reflow soldering batteries, regardless of their intended use. If you're going to continue a manual operation to solder one pin, I'd suggest that you just solder the entire component in by ha

First, don't exceed the maximum temperature of the battery, say 85*C [I don't know your specifics] Second, don't short the terminals of the battery. Third, the best way to wave solder a battery is: * Insert an insulating tab between the battery an

Both the coin and the device flange that is soldered to the coin have a gold finish. A solder preform is placed in the pocket of the coin before the device is placed prior to reflow. Solder adhere's to both surfaces

Coins are sometimes used on PCB's with RF Power Field Effect Transistors. These boards are usually mounted in an housing. They provide a ground path for the transistor to the PCB and thermal path to the housing. The coins are usually made of aluminu

We can't let this thread pass-by without trying to learn more about these 'coins.' What's the deal? * Are they like currency, money? * Are they coin-shaped metal slugs? * Why are they on a circuit board? What's their purpose? * Can you attach a pict
