-==== Resources: ==== +What are the reasons why the double-sided PCB board pad is not tinned? 
- + There are several cases in which the PCB board is not tinned. 
-[[resources:​vendors|Electronics Vendors]] - Places to find electronics ​and other stuff you might need+        1. The PCB circuit board is oxidized, ​and the PCB board is not tinned
- +        2. The temperature of the furnace is too low, or the speed is too fast, and the tin does not melt. 
-[[resources:​surplus|Surplus Electronics]] - Places to find stuff you didn't know you needed+        3. Solder paste problem, ​you can replace another solder paste try
- +        4Battery problem, this is the most common problem, because the battery is generally stainless steel, to be plated with a layer of chromium to tin
-[[resources:​pcb|PCB Manufacturers]] - This deserves its own category ​Prototype through production quantities+        If the plating layer is oily or poorly plated, it will not be tinned. You can use a soldering iron to see if it can be soldered. Or put some solder paste on the battery, and then use the desoldering station or the electric heating table to see if the battery can be tinned
