The invention discloses a punching process for FPC finished double-sided adhesive non-tearing film. The double-sided adhesive with the stripping film is pasted on the front of FPCa, and the back of FPCa is no longer pasted with low adhesive film. The FPCa product with double-sided adhesive is placed on the punch etching tool die for forming processing. When punching, the punching depth needs to be controlled to ensure that the double-sided adhesive film is not broken, and the FPCa is facing upward at this time. That is to say, the LED is facing up, after the forming process is completed, the FPCa product mould is taken out, the FPCa and double-sided rubber waste are discharged from the cut section of the product, and only the single product and the whole double-sided rubber separating film are retained. Finally, the finished product is inspected, and the finished product is packaged and shipped after the inspection is completed. The punching process of the double-sided adhesive free-tearing film of the FPC product is introduced. After forming and processing, the FPC component with double-sided adhesive material can be assembled directly by removing the upper stage without pre-tearing the double-sided adhesive film. The operation time of the tearing film operation is saved, the operation is simplified and the manpower is saved.

一种FPC成品双面胶免撕离型膜的冲切工艺
本专利技术属于FPC成品加工
,具体涉及一种FPC成品双面胶免撕离型膜的冲切工艺。
技术介绍
柔性电路板(简称FPC)是以聚酰亚胺或聚酯薄膜为基材制成的一种具有高度可靠性,绝佳的可挠性印刷电路板。具有配线密度高、重量轻、厚度薄、弯折性好的特点。原有的FPC产品作业工艺是在冲切之前,如图1中所示LB或FPCa背面贴低粘着胶片,正面贴带离型膜的双面,LED灯朝下从FPCa正面冲切,将双面胶离型膜、双面胶和FPCa三层材料一起冲断,粘在背面的低粘着胶片上出货(低粘着胶片仅为包装材料),双面胶离型膜同LB成为单体,要撕掉离型膜时必须对每一条LB分别撕离,造成作业繁琐且浪费时间,同时还提高了制作成本。
技术实现思路
本专利技术的目的在于提供一种FPC成品双面胶免撕离型膜的冲切工艺,以解决上述
技术介绍
中提出的问题。为实现上述目的,本专利技术提供如下技术方案:一种FPC成品双面胶免撕离型膜的冲切工艺,包括以下步骤:S1,将带离型膜的双面胶贴在FPCa正面,且FPCa的背面不再贴低粘着胶片;S2,将贴好双面胶的FPCa产品置于冲床蚀刻刀模上进行成型加工,此时FPCa正面朝上,即LED面朝上;S3,成型加工完成后,将FPCa产品模具上取出,从产品的裁断面将FPCa及双面胶废料排掉,只保留完成单支产品及整个双面胶离型膜;S4,最后将完成后的产品进行检验,检验完成后进行包装出货。优选的,步骤S2中,冲床蚀刻刀模包括定位上模和放置PFCa产品的底座,其中定位上模还包括设置在四角处的导柱,底座上设置有与导柱相卡合的柱孔,且FPCa产品设置 ...
