Poly Dome Custom Matrix Design Digital Printing Membrane Keypad Switch Supplier In China

Poly Dome Custom Matrix Design Digital Printing Membrane Keypad Switch Supplier In China

Product spec :

1)Material---for front or face overlay

The three usual materials utilized for the graphic overlays are:

Lexan/PC(Polycarbonate),Mylar/PET(Polyester ,and Vinyl(PVC)

Polyester offers the best flex life and chemical resistance .

Polycarbonate offers better weathering characteristics and ink adhesive .

PVC are cost saving when the overlay is textured,but it is not environmental.

Surface finishes include velvet textured ,anti-glare matte, gloss clear ,selectively textured and anti-microbial .

2) Embossing--rim embossing pillow embossing dim embpssing

Graphic overlays can be embossed in order to insert domes (tactile), leave space for mechanical keys and provide tactile indications Pedestal embossing

3)Windows ----for display function

1. tintedwindows

2.transparent finishes windows

Integral display windows and LED indicators can be easily incorparated into the membrane switch design .

4)Keys/buttons

Tactile keys--- metal dome or poly dome

Non-tactile--silver printing spot

Adding extra parts on the switch to get the crisp effect--Metal snap domes. it can be provided in several different size,shape and force according to the interface .

Wide range of domes is available:

· Ø 6 to Ø 16 mm

· 150 g to 550 g actuation force

· Typical life greater than 1M cycle

· Dimple and non-dimple versions available

· Round, Side Cut, Legged

· Dome plating options available

5) Embeded LEDs-

miniature LED, LED colors:white, yellow, orange, green, red, etc.

Surface mount single LED's can be integrated into a membrane switch circuit .

A standard membrane switch is not thick enough to accomomodate the height of most surface mounted LEDs.For this reason ,The overlay is generally embossed in the window erea .

6)Cable

is an extension of the printed circuit and is used to communicate with your device

7)Types of connector

1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector

A male or female connector can be fitted to the end of the tail .Solder pins can also be provided.

A pin of .01” is the most common ,Using a ZIF connector will be reduce the membrane switch cost as the tail will not need own connector and the pitch can be reduced to 1mm.

8) EMI / RFI / ESD Shielding

use an aluminum foil shielding / a clear ITO electrical conductive polyester

Using an aluminum foil shielding / a clear ITO electrical conductive polyester

Shields can be designed for the following :

a.ESD ( Electrostatic Discharge )

b.EMI ( Electromagnetic interface )

c.RFI (Radio Frequency Interface )

9) Adhesive ----mostly 3M-double-side glue
