Tips for Preventing Scratches on Membrane Switch Windows

Maintaining the Integrity of the Connection Between the Membrane Switch and Display Window

Ensuring Transparency Meets User Requirements

When it comes to preventing scratches on the windows of membrane switches, the connection between the switch and display window must be secure. Users have strict requirements for window transparency, with no room for defects. Quality control is crucial, as users often use the glass quality to assess the display window. Keeping in mind that the customer is always right, how can we ensure the quality of the window membrane switch? It all starts with a strong focus on quality, with rigorous control over every step of production. The window and key of the membrane switch are interconnected, with a complex production process that requires careful consideration at every stage to prevent scratches.

Control raw materials, transparency and scratch test levels for purchased raw materials. For the material selection of membrane switch with display window, must choose anti-scratch material, the front anti-scratch grade is particularly important, the raw material purchased is a certain material has a protective film on both sides, when the material is cut, will not cause damage to the material, the material choice is improper, the window scratches are difficult to control. In a printing environment, printing usually takes place in a dust-free workshop, dust-free is only relative, semi-automatic screen printing, window exposure time is longer, especially when there are many color film switches, consider printing water-based protective paint on windows in the second process so that subsequent processes can protect windows from dust damage, and then covering the windows with protective film after the last process. Automatic printing of each printing process must be covered with protective film, at the same time note that rubber can not be attached to the dust particles to prevent window scratches.Standardized operation, every step of the production process, must not be allowed to touch the window area, at the same time prohibit cleaning the window. Both cover the window with their fingers, leaving marks, and then gently wipe away any possible damage. Film switch production involves a large number of mold, mold window area must be smooth and bright, in the production process to check whether there is debris on the mold to prevent extrusion window. Screen surface to pay special attention, can not have trachoma, prevent screen surface oil leakage. After printing, the finished board must be double-sided composite adhesive connector assembly. Usually after the circuit assembly is completed, do the last process paste panel, remove the back of the protective film paste panel, paste immediately after the window area covered with protective film.
