Rechan Electronic Technology Co., Ltd. is a manufacturer specializing in customizing confidential and tamper-proof flexible circuit boards. High-precision anti-tampering flexible circuit boards are mainly used in security equipment, electronic door locks, anti-theft equipment, safes, bank cards and other products. Pure circuit boards can also be made into signal transmitting and receiving antennas. The anti-tampering flexible circuit board is assembled with metal shrapnel to form the Metal Dome, which also has the functions of key switch and confidentiality, anti-tampering and anti-theft.

When an external force attempts to open the circuit board, the silver wire on the circuit board will automatically disconnect, and the IC connected to the circuit will initiate a self-destruct program to clear all data.

Rechan Electronic Technology Co., Ltd. is a manufacturer of Poly Dome and Metal Dome. Poly Dome and Metal Dome are also called upper circuits, which together with PCB assembly form a key switch. Rechan Technology has advanced Poly Dome and Metal Dome design experience and a professional technical team.

Poly Dome is made of imported PET. Low-resistance conductive silver dots are printed on the PET, and then molded into a spherical convex state. The Poly Dome buttons feel comfortable, have short contact time with the gold fingers on the PCB, and the buttons rebound quickly.

Metal Dome also uses PET, but instead of printing conductive points, it uses metal shrapnel as the switch button. The buttons have a long service life and the button strength is controllable.
 

 

A transparent self-adhesive film is used on the surface, and a metal shrapnel is pasted on the bottom. A gasket is added to the non-shrapnel area to protect the shrapnel. Ventilation grooves are connected between each elastic piece to prevent air below the button from affecting the feel of the button when the button is pressed. This product is called Metal Dome.
The other type does not require metal shrapnel, but directly prints conductive silver dots and bulges on the surface of PET to achieve the same effect as Metal Dome. This product is called Poly Dome.

The functions and usage methods of Metal Dome and Poly Dome are exactly the same. They are both attached to the PCB or flexible circuit board below. Metal Dome and Poly Dome are equipped with silicone buttons or plastic buttons, which together form a button switch. When assembling, pay special attention to the integration of three points: the center point of the silicone button or plastic button, the center point of the Metal Dome or Poly Dome, and the center point of the button area of the PCB or flexible circuit board. The three center points should be aligned vertically. Only in this way can the key function and feel be achieved to the best effect.
 

Poly Dome and Metal Dome have been widely used in various industrial and household appliances such as intelligent electronic measuring instruments, medical instruments, computer controls, CNC machine tools, electronic scales, communication equipment, electronic game consoles, etc.

Rechan Electronic Technology Co., Ltd. is a manufacturer of FPC flexible circuit boards. The flexible circuit board adopts a matrix circuit design, with conductive silver paste printed on multiple layers of PET material to form a multi-grid matrix switch circuit. Each grid is a small touch switch. Press the button area lightly, the button will instantly contact and conduct, and the response will be sensitive. Multi-layer designed FPC flexible circuit boards are widely used in early childhood education equipment, such as point reading machines, and toy wall charts with numbers or English letters printed on them.

The FPC flexible circuit board inside the reading machine adopts a large-area matrix switch circuit design.
The flexible circuit board adopts a three-layer structure of upper, middle and lower layers: the upper and lower layers are printed flexible circuit boards, and the middle layer is a spacer with double-sided tape. The spacer can stick the upper and lower layers of flexible circuit boards.
When an external force is applied to the button area, the contacts of the upper and lower flexible circuit boards are connected to form a button switch.


The FPC flexible circuit board adopts a double-layer printing design. There are printed conductive silver paste lines on both sides of the PET. The connection point is a small hole that penetrates both sides. The conductive silver paste in the hole connects the silver lines on the front and back sides. The light green part in the picture is printed insulating UV oil.
