FPCs are circuit boards characterized by their flexibility and ability to bend, and they are widely used in various electronic devices. During the manufacturing process, FPCs are typically connected to other electronic components via connectors (such as male connectors or sockets). The purpose of testing FPC connector crimping is to ensure the reliability and durability of the connection. The following is a general description of the steps involved in this test method:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4906\" src=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/07\/fpc.jpg\" alt=\"Flexible Printed Circuit Boards\" width=\"500\" height=\"300\" srcset=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/07\/fpc.jpg 500w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/07\/fpc-300x180.jpg 300w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/07\/fpc-267x160.jpg 267w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/07\/fpc-400x240.jpg 400w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<h2>Testing of Silicon-Aluminum Foil Auxiliary Materials:<\/h2>\n<ul>\n<li>Visual Inspection: The surface should be smooth and free of cracks, fissures, particles, bubbles, pinholes, and foreign matter.<\/li>\n<li>Thickness: Measure using a micrometer at five points, read the measurements, and record the data.<\/li>\n<li>Dimensions: Measure using a ruler or tape measure, taking measurements at equal intervals, then read and record the data.<\/li>\n<li>Temperature Resistance: Continuous heating temperature resistance test on silicon-aluminum foil (temperature: 185\u00b0C; pre-pressing: 10 s; molding time: 120 s; pressure: 100 kg\/cm\u00b2; continuous operation for 5\u20137 days)\u2014no embrittlement is permitted.<\/li>\n<li>Silicone Oil Leaching: During continuous temperature-rising heat resistance testing of the silicon-aluminum foil (temperature: 185\u00b0C; pre-pressing: 10 s; molding time: 120 s; pressure: 100 kg\/cm\u00b2; continuous operation for 5\u20137 days), the silicon-aluminum foil must not exhibit any silicone oil leaching.<\/li>\n<\/ul>\n<h2>Testing of Fiberglass Cloth Accessories:<\/h2>\n<ul>\n<li>Visual Inspection: The surface should be smooth and even, free of wrinkles, cracks, particles, and foreign matter.<\/li>\n<li>Thickness: Measure using a micrometer at five points, read the measurements, and record the data.<\/li>\n<li>Dimensions: Measure using a ruler or tape measure, taking measurements at equal intervals, then read and record the data.<\/li>\n<li>Temperature Resistance: The fiberglass cloth has undergone continuous heating tests (temperature: 185\u00b0C; pre-pressing time: 10 seconds; molding time: 120 seconds; pressure: 100 kg\/cm\u00b2; continuous operation for 5\u20137 days) and shows no signs of embrittlement; it is therefore approved for use.<\/li>\n<\/ul>\n<h2>Testing of Auxiliary Materials for Fired Iron Plates:<\/h2>\n<ul>\n<li>Visual Inspection: The surface should be smooth and free of cracks, fissures, particles, bubbles, pinholes, and foreign matter.<\/li>\n<li>Thickness: Measure using a micrometer at five points, read the measurements, and record the data.<\/li>\n<li>Dimensions: Measure using a ruler or tape measure, taking measurements at equal intervals, then read and record the data.<\/li>\n<li>Temperature Resistance: Sintered iron plates undergo continuous heating tests (temperature: 185\u00b0C; pre-compression: 10 s; forming time: 120 s; pressure: 100 kg\/cm\u00b2 for 5\u20137 days of continuous operation) and do not exhibit brittle fracture; fracturing is permissible.<\/li>\n<li>Silicone Oil Leaching: Subject the fired iron plate to a continuous temperature rise during a heat resistance test (temperature: 185\u00b0C; pre-pressing: 10 seconds; molding time: 120 seconds; pressure: 100 kg\/cm\u00b2; continuous operation for 5\u20137 days).
