How does FPC control the thickness of plated copper and hole copper?Answer:Generally, the thickness ratio of plated copper and hole copper is 1:1.5, such as plated copper 6-8um, hole copper will reach 10-15um; Local copper plating is not acceptable.2. What are the base material? What's the difference between Pl and PET materials?Answer:Materials: Polyimide (PI) and Polyester (PET) Temperature resistance is different, Pl operating temperature can reach 130 degrees Celsius, the highest can withstand 250 degrees Celsius; PET operating temperature is only 50 degrees Celsius, the highest can withstand 105 degrees; FPC's common material is PI.3. What are the common thicknesses of cover layer?Answer:The cover layer includes adhesive, like 50um cover layer (25um Pl+25um adhesive), 27.5um cover layer (12.5um Pl+15um adhesive)4. What are the common surface treatments of FPC?Answer: ENIG, Gold plating, OSP, Immersion silver, ENEPIG (can't do HASL)5. What are the types of FPC stiffener?Answer:Pl stiffener, thickness selection:0.075mm, 0.1mm, 0.125mm, 0.15mm ,0.175mm, 0.2mm,0.225mm, 0.25mm.FR4 stiffener, thickness selection:0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm~1.6mmStainless steel stiffener, thickness selection: 0.1mm, 0.2mm Aluminum stiffener, thickness selection:1.0mm, 2.0mm (Special, rarely used)/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
