The Manufacturing Process of Membrane Switches: Quality Control and Standards

Material Selection for Membrane Switches

The selection of materials for a membrane switch is important because it determines the quality of the finished product. That is why we take time in sourcing quality materials such as where the thumb and fingers touch the screen and finger contact, which offer good friction and resistance. In addition, the choice of adhesives guarantees the strength of each layer, thus allowing the membrane switches to withstand stress over many years.

Printing Techniques in Membrane Switch Production

Printing is vital for the proper formation and function of the membrane switches. In this case we use well known techniques of screen printing in the application of conductive inks as well as graphics elements. This helps achieve bright clear images but with inclusive electricals needed for service. For the advantages and properties of these elements to last, proper curing processes have to be observed.

Assembly and Layer Bonding

The assembly process involves stacking the layers printed with graphics, the spacers and the circuits into a membrane switch. For effective plating the alignment is critical. The indicating layers such as graphic overlays are bonded in air tight/tighten surroundings as these are crucial to the final appearance and performance of the membrane switches.

Membrane Switch Construction Quality Testing and Control

To ensure high quality membrane switches, we create stringent quality criteria that every switch needs to meet as making switches that have received poor internal quality control would negatively impact the whole base, therefore every membrane switch created is tested for its electrical performance, lifespan, and working capabilities, as these make a membrane switch. They would also include tactile response and environmental resistance testing to ensure they pass the required grade.

Membrane Switch Construction Compliance to Standards and Certifications

All of our switches will pass international quality certificate requirements for membrane switches, passing ISO certs and RoHS compliance, so they are both efficient in their use and environmentally friendly, our dedication to standards will reflect off of the tests and safety features of the switches. i.e. reliability.
