Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, the embodiment provided by the present invention, a kind of manufacturing method of novel FPC, comprises the following steps:

[0025] S1: The copper base material 1 and the nickel base material 2 are heated and combined by rolling; after annealing, they are divided into strips to form substrates. The copper substrate 1 has a thickness of 70 μm, and the nickel substrate 2 has a thickness of 30 μm.

[0026] S2: After the substrate is chemically cleaned, one side is covered with a film and then pressed and cured;

[0027] S3: After the substrate is chemically cleaned, the dry film is pasted, exposed, developed and etched for the coil circuit, and the excess dry film is removed; the front of the substrate is exposed, developed and ...

Abstract

The invention discloses a manufacturing method of a novel FPC. The manufacturing method of the novel FPC comprises the following steps: S1: a copper base material and a nickel base material are heatedand rolled and clad; stripping is performed after annealing so as to form a substrate; S2: after the substrate is chemically cleaned, single-sided film coating is performed and then pressing and solidifying are performed; S3: after the substrate is chemically cleaned, a dry film is adhered, and exposing, developing and etching of a coil line are performed and the excess dry film is removed; S4, after the film is removed in the step S3, cleaning is performed, a covering film is adhered and pressed and solidified; S5, the substrate is baked and then the solder paste is printed, SPI detection isperformed and then reflow soldering is performed on an SMT automatic mounting machine, and glue dispensing is performed on the surface of the substrate and then the FPC is prepared. The aluminum material is directly soldered with the FPC so that the original bridging processing through the nickel sheet can be simplified, a large amount of manpower and processing cost can be saved, the productionefficiency can be improved, the quality and the yield rate can be improved and safety and reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of FPC, in particular to a method for making a novel FPC. Background technique [0002] At present, the raw materials used in FPC are all soft copper foil substrates, which are processed to make FPC finished products to realize data transmission. In the new energy power battery harness FPC, the traditional FPC is also used to weld with tin and nickel sheets to realize the pressure collection of the battery pack and the collection of the temperature of the battery cell. The finished battery connection module adopts the bonding method of aluminum bar and aluminum wire, and the other end of the aluminum wire is bonded with nickel sheet. Or aluminum bar and nickel sheet laser welding connection. FPC has many processing procedures, long production process, low production efficiency, large equipment investment; high difficulty in quality control; many types of materials, and long procurement cycle.
