What screw size, tightening torque, and tightening sequence are recommended for Sigma TDS or LCD mounting holes? - FAQs | Manufacturer of Resistive | PCAP Touch Screen | PenMount Touch Screen Controller - AMT

For the integrated Sigma TDS/LCD mounting holes, the Integration Guide recommends M3 screws tightened to 4.0 to 5.0 kgf-cm. Select the screw length so it does not exceed the module frame's maximum thread depth. Avoid excessive downward force or torque because it can deform the frame and transfer localized stress to the LCD or bonding area. For modules with multiple mounting points, tighten the screws gradually in a crosswise pattern so the clamping load is distributed evenly and the housing or bracket is not distorted. Certified resistive, projected capacitive (PCAP) touch screens and PenMount touch screen controllers meeting international standards, ISO, UL E331240-A1-UL, REACH, and RoHS. All touch screen products are supplied with flexible production quantity and long term support.
