We will partner with you and share our expertise to determine the type of circuitry and features that enable your product to function at its highest level, with an optimal experience for the end user. Of course, your membrane switches will be manufactured with high quality materials and meet your exacting specifications. In fact, the membrane keypads are playing vital role in all multiple electronic industries. It doesn’t matter that how electronic gadgets have become extra modern and complex in this technological era. Because membrane keypad manufacturers deeply know how to produce ideal solutions for all these growing variety of applications. Lustre-Cal Co. is a custom manufacturer of chemical-resistant membrane switches.
Tradeindia is one of the global platform to provide local and international market and customers, it helpful to make my business trực tuyến presence and create more visibility. Due to the strict sealing requirements of process, the switch contacts are proof against hazardous gas erosion, oxidization, proof against water/dust/oil, thus suitable for various harsh environments. Direct channel to find the tailored membrane switch right for your machine & equipment.
Membrane keypad construction will typically be either “single layer” or “double layer” construction., depending on the features required. For single layer keypads, one liên hệ layer is usually printed on the reverse side of the graphic overlay panel. For double layer construction, the top circuit is printed on a separate layer.
On a non-tactile switch, the bottom side of the overlay is connected to a conductive pad, or an upper circuit layer is printed with conductive traces. When the overlay is pressed down the conductive traces connect to the lower circuit layer which sends a signal to a printed circuit board. For the Rigid circuit membrane switches, the circuit is rigid printed circuit board. The reason why the China membrane switch panel is widely used is because of some very superior performances. It can fulfill various requirements of users, from industrial equipment to medical equipment. “Customer first, quality first, create value together.” We continue to pursue technological progress, the win-win between clients and us.
In simple terms, to create a membrane keypad we’re basically adhering a printedoverlay panel over a flexible printed circuit. Other technologies such as Led’s, Antennas, capacitive sensors can also be incorporated into the assembly. All technologies must be incorporated without lumpiness to the appearance of the membrane switch assembly. Membrane switches and keypads are a fully customisable solutions for Human – Machine Interface requirements. Each product we design and manufacture is unique and has its own requirement regarding environmental, mechanical, electrical and physical appearance properties. With our decades of experience, Sun Industries is able to help you through the specification process to make sure your products HMI solution is suited perfectly.
Our adhesives are resistant to humidity, UV, water, temperature, and chemicals. Adhesive Layers – we use double-sided adhesive polyester films that are coated with the layer of acrylic adhesive. This layer is mainly useful for gluing different types of films and circuits together, then for the enclosure of keypad and supports mounting of the plates. BOPLA manufactures high-quality keypads with copper-laminated base membranes, galvanically silver-plated (gold-plated on request). The copper-laminated material is extremely flexible, so there is almost no possibility of breaks to the membrane cable, and problems such as silver migration are practically impossible. Testing and debugging many times to avoid errors during membrane switches manufacturing process.
With no perforations required for the membranes to interact, membrane keypads are easy to clean, resistant to water damage and UV radiation, and devoid of crevices for contaminants to build up. Back Adhesive Layer – This second layer of acrylic adhesive binds the membrane switch assembly to the product enclosure. Dome Retainer / Upper Circuit Layer – This is one of two potential membrane layers with conductive and dielectric circuitry printed onto it. Tactile switches will typically use a dome retainer in place of this layer.
We fabricate tooling and compounding material in house for rubber & plastic parts, as the good quality products, excellent service and management. We ensure all the parts supply to our customer is RoHS Directive Compliant green products “Lead Free Initiative”, all of our products passed European environment standards. If you have any other requirements or questions, please do not hesitate to liên hệ us. We appreciate all of your tư vấn and look forward to your continued tư vấn in the furture.
Optically clear adhesives are used to bond display components to improve contrast and brightness, offering optical, mechanical, and electrical performance benefits. Our team of engineers and designers can provide unique innovation to your process. Our expertise in human – machine interaction can supply your application with the ease of use required to compete in an increasingly competitive marketplace. If the face of your device needs to be viewable in direct sunlight or bright light, BTI engineers can help to choose the right materials for your application. Gently laminate the switch starting from the side with the removed adhesive liner, using a soft roller, apply slight pressure as rolled across the top surface of the switch. Perimeter frame of adhesive that protects your circuitry from any moisture ingress.
