在进行SMT之前，首先需要将FPC精确固定在载板上。特别需要注意的是，从FPC固定在载板上以后，到进行印刷、贴装和焊接之间的存放时间越短越好。载板有带定位销和不带定位销两种。不带定位销的载板，需与带定位销的定位模板配套使用，先将载板套在模板的定位销上，使定位销通过载板上的定位孔露出来，将FPC一片一片套在露出的定位销上，再用胶带固定，然后让载板与FPC定位模板分离，进行印刷、贴片和焊接。带定位销的载板上已经固定有长约1.5mm的弹簧定位销若干个，可以将FPC一片一片直接套在载板的弹簧定位销上，再用胶带固定。在印刷工序，弹簧定位销可以完全被钢网压入载板内，不会影响印刷效果。
Before SMT, the FPC needs to be accurately fixed on the carrier plate. It should be noted that the shorter the storage time from FPC fixed on the carrier plate to printing, mounting and welding, the better. There are two kinds of carrier plates with and without locating pins. The carrier plate without locating pin shall be used together with the locating template with locating pin. Firstly, the carrier plate shall be sleeved on the locating pin of the template to expose the locating pin through the locating hole on the overload plate, and the FPC shall be sleeved on the exposed locating pin one by one, and then fixed with adhesive tape, and then the carrier plate shall be separated from the FPC locating template for printing, pasting and welding. Several spring locating pins about 1.5mm long have been fixed on the carrier plate with locating pins. FPC can be directly sleeved on the spring locating pins of the carrier plate one by one, and then fixed with adhesive tape. In the printing process, the spring locating pin can be completely pressed into the carrier plate by the steel mesh without affecting the printing effect.
方法一（单面胶带固定）：用薄型耐高温单面胶带将 FPC 四边固定在载板上，不让 FPC 有偏移和起翘，胶带粘度应适中,回流焊后必须易剥离,且在FPC上无残留胶剂。如果使用自动胶带机，能快速切好长短一致的胶带，可以显著提高效率型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵，节约成本，避免浪费。
Method 1 (fixing with single-sided tape): fix the four sides of FPC on the carrier plate with thin high-temperature resistant single-sided tape to prevent offset and warping of FPC. The viscosity of the tape should be moderate. It must be easy to peel off after reflow welding, and there is no residual adhesive on FPC. If the automatic belt conveyor is used, the belt with the same length can be cut quickly, which can significantly improve the efficiency, save the cost and avoid waste.
