Best manufacturer of Battery Holder & Connectors in China
FBelec specializes in producing all kinds of battery boxes, battery buttons, battery seats, button battery seats and 9V battery buttons, external power battery boxes of safes, rechargeable battery boxes of safes and emergency battery boxes.
Button battery base is used to load button battery, which is generally welded on PCB board to facilitate button battery power supply module clock or other consumer electronic products.
Installation method of battery base
There are two installation methods of button battery base, one is plug-in type and the other is patch type.
Suggestions for battery base selection
Installation aging;
Dimensional accuracy and drape;
Button battery is the key component in many micro instruments;
The cost of button battery base is generally plastic materials such as LCP, PPS and PBT, metal shrapnel materials such as iron, steel and copper (metal shrapnel electroplating treatment such as nickel, tin and gold). There are differences in temperature resistance, corrosion resistance, drop, conductive stability and exquisite appearance of different materials;
If there are requirements for PCB space, battery shrapnel (pure hardware) can be selected, but the positive and negative of battery shrapnel are divided into two parts separately, and one step is added to the assembly. For example, for individual remote controls, positive battery shrapnel, negative shrapnel or gold, nickel and tin sinking process can be used.
Common Problem
How to identify the positive and negative poles of button battery base
Generally, the button battery marked with "+" is the positive pole, and the back is the negative pole; The shell at the edge of the button battery is also positive, so most button batteries loaded on the button battery base are positive upward, because there are metal shrapnel at the side end of the button battery base to prevent the button battery from falling out. This is the positive electrode metal shrapnel, which will cling to the positive electrode edge of the button battery. Due to the large-area electrode contact of the positive electrode metal shrapnel, Effectively improve the stability of electrode contact; If the positive and negative poles of the button battery are replaced, the battery can also be stuck, but the battery will be short circuited.
How to remove the battery from the button battery holder
The accessories with button battery base on the product are easy to replace the old and new button batteries. The metal shrapnel can be moved easily. If you look carefully, you can find the method to take out the button battery. Some button battery base designs may need a small insulating plastic sheet to assist in taking out the button battery.
Plug in type
The button battery base cannot be welded with tin;
Add flux to reduce surface tension and improve wettability;
Increase welding temperature;
Replace the solder paste.
