When the requirement of a membrane keypad comes to water proofing, it is very often related to the term: IP Liquid Ingress Protection Marking.

Central Midori has its first product IP67 certified in the Year 2007.

A conventional membrane keypad comprises subparts like the Graphic Overlay, Overlay Adhesive, Dome Holder, Spacer, Conductive Printed PET, Backer & components like Tactile Domes & LEDs. The Gasket is integrated with all mentioned above to construct a water proofing membrane keypad.

Through-Hole Printing vs. Through-Hole Plating

In the manufacturing of Printed Circuit Board, through hole plating remains a complex operation. It involves wet chemical processes including deposition of metals by metallization and electroplating techniques. Although direct metallization has contributed to reduce the number of steps and chemicals involved in the process, it is still the source of a lot of anguish among the engineering community.

Printed Electronics is emerging as the technology that will replace traditional subtractive PCB manufacturing. With no wet chemistry it is widely considered a “green process” and falls in the category of additive technology.

As a South East Asian leader of Printed Electronics, Central Midori pioneered in the development of a proprietary through-hole printing process using conventional screen-printing technique and silver conductive ink.

Substrate is generally made of polyester or polycarbonate film with thickness comprised between 50 and 125 microns - thinner is possible but generally requires heat stabilization first.

 

Top 4 Types of Backlighting for Membrane Keypad

Too often, we get frustrated when working in a dark environment with a handheld device / equipment which does not have an illuminated keypad. This forces us to bring along an alternative light source such as a torchlight or mobile phone just to operate in the dark.  However, this issue can be easily resolved by having one of several types of illuminated membrane keypad.
