Abstract
The invention discloses the FPC production methods of a kind of silk-screen and dispensing production coating, it includes step S1, silk-screen, is covered no-coverage using silk-screen halftone, and will be exposed to silk-screen region, the halftone figure of printing is unilateral to inside contract 0.75 to 1.25mm compared with design and printing figure；Ink is printed to copper foil base material surface to silk-screen region using screen printer, forms silk-screen figure；S2, dispensing carry out dispensing using dispensing region of the dispenser to copper foil base material surface, fill up the lack part between silk-screen figure and design configuration；Dispensing region is compared with design configuration, equal externally expanding single edge 1.5mm；S3, baking heat 10min under conditions of the FPC after dispensing is placed in 160-180 DEG C.The present invention can directly reduce production process, especially large size product (such as: signal acquisition FPC in accumulation of energy, batteries of electric automobile PACK), can be reduced the dependence to big table top customization press table, save board buying, manpower and time cost.
Description
Technical field
The present invention relates to flexible print circuit technical field, the FPC system of especially a kind of silk-screen and dispensing production coating
Make method.
Background technique
Currently, tradition FPC protects electronic circuit as coating using cover film, need to be cut into cover film in advance
Then figure is fitted on copper-based material, then pressed and toasted, and makes coating in conjunction with copper-based material.
This process needs to undergo 6 processes that could complete (cover film sawing sheet → drilling → punching → fitting Copper base material → pressure
Conjunction → baking).Moreover, the conventional production equipment that presses needs to add by several times when product size is larger (greater than 350mm*500mm)
Work can directly generate quality risk and time cost is caused to get higher.
When customizing big table top press equipment for large size product production, equipment for customizing fabrication cycle is long, and technical parameter is not
Stablize, the FPC product quality for also resulting in production is unstable (for example overburden cover uniformity is bad).
Summary of the invention
The technical problem to be solved by the present invention is in view of the above shortcomings of the prior art, provide a kind of silk-screen and dispensing production
The FPC production method of coating.
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of silk-screen and dispensing make coating
FPC production method comprising following steps:
S1, silk-screen are covered no-coverage using silk-screen halftone, and will be exposed to silk-screen region, the halftone figure of printing
Shape is unilateral to inside contract 0.75 to 1.25mm compared with design and printing figure；Ink is printed to copper foil base material table using screen printer
Face to silk-screen region, form silk-screen figure；
S2, dispensing carry out dispensing using dispensing region of the dispenser to copper foil base material surface, fill up silk-screen figure and design
Lack part between figure；Dispensing region is compared with design configuration, equal externally expanding single edge 1.5mm；
S3, baking heat 10min under conditions of the FPC after dispensing is placed in 160-180 DEG C.
Further, in the step S1, the scraper angle of screen printer is 17.5 degree.
Further, in the step S1, the printing pressure of screen printer is 4 to 6.5kg/cm2。
Further, in the step S1, the silk-screen halftone height of screen printer is 7 to 10mm.
Further, the ink is PI ink.
Further, it in the step S3, is toasted in hot-air oven or continuous tunnel furnace.
Further, the viscosity of the ink is 190 to 230dP.s.
The beneficial effects of the present invention are:
1, do not change product structure, do not change product material
After the completion of production, product structure will not change；The embodiment of the present invention uses PI ink, tradition covering membrane process
It is also PI material, after the completion of production, product material will not be changed.
2, reduce letter using present invention process method and manufacture process
Modulation ink makes it suitable for silk-screen mode operation, is required with meeting functional characteristics such as product thickness, electrical etc..Silk-screen
It is the normal process steps of FPC production, to equipment, controls the not additional requirement of tool, employee's operative skill, manufacturing parameter is set to
Corresponding parameter can produce.Precise glue dispensing is SMT normal process steps, and to equipment, to control tool, employee's operative skill not additional
It is required that manufacturing parameter, which is set to corresponding parameter, to be produced.
Specific embodiment
The present invention is described in further detail below.
Embodiment 1, a kind of FPC production method of silk-screen and dispensing production coating comprising following steps:
S1, silk-screen are covered no-coverage using silk-screen halftone, and will be exposed to silk-screen region, the halftone figure of printing
Shape is unilateral to inside contract 0.75 to 1.25mm compared with design and printing figure；Ink is printed to copper foil base material table using screen printer
Face to silk-screen region, form silk-screen figure；For example, using the halftone of 36T to 51T, it, can under the conditions of the manufacturing parameter of setting
So that overburden cover reaches 20 to 45 μm.Silk-screen on thickness primarily to reach requirement.
S2, dispensing carry out dispensing using dispensing region of the dispenser to copper foil base material surface, fill up silk-screen figure and design
Lack part between figure；Dispensing region is compared with design configuration, equal externally expanding single edge 1.5mm；Generally, precise glue dispensing machine exists
Liquid ink is quantitatively conveyed when dispensing, regulates ink viscosity, and under the conditions of the manufacturing parameter of setting, coating pattern precision can
To reach ± 0.10-0.15mm.
S3, baking heat 10min under conditions of the FPC after silk-screen twice is placed in 160-180 DEG C.With traditional cover film
Technique is compared, and cover film baking is toasted 120 minutes under the conditions of being 160 DEG C.The process time of the invention is shorter.
Specifically, the silk-screen parameter of screen printer: scraper angle is 17.5 degree in the step S1.The printing pressure of screen printer
Power is 4 to 6.5kg/cm2.The silk-screen halftone height of screen printer is 7 to 10mm.
Specifically, the ink is PI ink.The viscosity of the ink is 190 to 230dP.s.Using Zhi Qi section, Shenzhen
The ink product of skill Co., Ltd model PI-1100.
Specifically, being toasted in hot-air oven or continuous tunnel furnace in the step S3.
The above embodiments are merely illustrative and not limiting of the invention, therefore all according to described in present patent application range
The equivalent change or modification done of method, be included in the scope of the patent application of the present invention.
