各种矩阵显示屏四周,都有数量多(可达4×128线)、密度高(可达0.3mm间距)的薄膜电极端子,将其同驱动线路连接虽有多种方法,但要保证完全可靠并不容易,因为这种微细电极端子的条引线连接技术,对于连接密度和连接质量都有很高要求。最近我们采用聚酞亚胺薄膜挠性印刷电路板,并使用再流焊方法,对矩阵屏薄膜电极端子进行引线连接,取得了较好的结果。 There are numerous (up to 4 × 128 lines) and thin (up to 0.3mm pitch) thin-film electrode terminals all around the various matrix displays. There are several ways to connect them to the drive line, but be sure Reliable is not easy because the strip lead connection technology for this fine electrode terminal has high requirements for connection density and connection quality. Recently, we have adopted the polyimide film flexible printed circuit board, and the use of reflow soldering method, the matrix screen film electrode terminals for wire connections, and achieved good results.
