Abstract
The invention relates to the field of substrate detection, in particular to a detection method of an FPC (flexible printed circuit) high-Tg glued substrate applied to vehicle-mounted LED (light emitting diode) lamp products. The method mainly comprises the following steps of (1) performing aging test on the FPC high-Tg glued substrate; (2) respectively performing a cold and hot impact test, a constant-temperature and constant-humidity test and a high-temperature storage test on the FPC high-Tg glued substrate. The method provided by the invention can be used for detecting whether the FPC high-Tg glued substrate has the heat-resistant performance and the environment-resistant performance or not and whether the dimension stability and the mechanical intensity can be maintained at high temperature or not, so that whether the electric performance of the substrate is reduced or not and whether the service life of a product can be influenced or not are determined, and the quality of the substrate is further determined.
Description
Technical field
The present invention relates to base material detection field, particularly relate to the detection method that a kind of FPC height Tg being applied in vehicle-mounted LED lamp series products has gum base materials.
Background technology
Flexible circuit board FPC have volume little, lightweight, 3D stereo rotating can be done and dynamically around advantages such as foldings.Its powerful advantage not only makes it be used in the traditional field such as consumer electronics product, can also be used for the vehicle-mounted high-end added value fields such as intelligent mobile phone terminal, LED lamp of automobile, automobile instrument panel, car engine.
At present, the application of FPC develops in the direction of diversification, and the application of traditional field has been tending towards saturated, and is in a day period for crescent benefit for the research of automotive field.Vehicle-mounted FPC is different from traditional F PC, and the requirement in its material, technique, quality and performance is unusual.In order to meet technique and the quality requirements of client in vehicle-mounted FPC, FPC Design and manufacture persons are also in the method for making of continuous Renewal Design theory and technique.But vehicle-mounted FPC determines the special of its materials and process due to the singularity of its purposes, in order to solve this singularity, first needs the selection difficult problem solving material from source.
FPC common substrate, at high temperature, may produce the quality hidden danger such as softening, distortion, melting.High Tg refers to the heat-resisting quantity of material, and Tg is higher, shows the rigidity that at high temperature more can keep material.For wiring board, that is to say and maintain size permanance and physical strength.Meanwhile, base material Tg is higher, and the feature such as moisture resistance, resistance to stability, cohesiveness, thermal decomposition, thermal expansivity also can corresponding raising and improvement.Now be badly in need of a kind of detection method to ensure that FPC height Tg has the quality requirements of gum base materials.
Summary of the invention
For the deficiency that prior art exists, a kind of FPC height Tg meeting quality requirements is the object of the present invention is to provide to have the detection method of gum base materials.
For achieving the above object, the present invention can be achieved by the following technical programs:
FPC height Tg has a detection method for gum base materials, it is characterized in that, comprises the following steps:
(1) gum base materials is had to carry out aging test to FPC height Tg;
(2) gum base materials is had to carry out cold shock testing, constant temperature and moisture test, high-temperature storage test respectively to FPC height Tg.
Further, in step (1), the aging temperature of aging test is 120 DEG C, and digestion time is 2h.
Further, in step (2), the low-temperature impact temperature of cold shock testing is-42 ~-38 DEG C, and the low-temperature impact time is 30min, and high temperature impact temperature is 123 ~ 127 DEG C, and the high temperature impact time is 30min, and number of shocks is each 500 times of high/low temperature.
Further, 10s is less than the switching time of low-temperature impact and high temperature impact.
Further, in step (2), the test temperature of constant temperature and moisture test is 83 ~ 87 DEG C, and test humidity is 83 ~ 87%, and test period is 990 ~ 1010h.
Further, in step (2), the test temperature of high-temperature storage test is 123 ~ 127 DEG C, and the storage time is 990 ~ 1010h.
The present invention can detect FPC height Tg has gum base materials whether to have thermotolerance and environment resistant, at high temperature can keep dimensional stability and physical strength, thus determine whether the electric property of base material declines, and can or can not affect life of product, determines the quality of base material further.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated:
FPC height Tg of the present invention has the detection method of gum base materials, mainly comprises the following steps:
(1) gum base materials is had to carry out aging test to FPC height Tg.
The test condition of aging test: aging temperature is 120 DEG C, digestion time is 2h.First carry out aging be thermal shock, constant temperature and humidity, high-temperature storage test pre-service.
(2) gum base materials is had to carry out cold shock testing, constant temperature and humidity respectively to FPC height Tg.Test, high-temperature storage test.
The test condition of cold shock testing: low-temperature impact temperature is-42 ~-38 DEG C, the low-temperature impact time is 30min; High temperature impact temperature is 123 ~ 127 DEG C, and the high temperature impact time is 30min; Number of shocks is each 500 times of high/low temperature, and the switching time of low-temperature impact and high temperature impact is less than 10s.Cold shock testing is in order to whether test material produces the situation of destruction or function deterioration under the continuous environment of very high temperature and pole low temperature in moment.
The test condition of constant temperature and moisture test: test temperature is 83 ~ 87 DEG C, test humidity is 83 ~ 87%, and test period is 990 ~ 1010h.Constant temperature and moisture test is the adaptability that analog equipment operates and stores under climatic environment.
The test condition of high-temperature storage test: test temperature is 123 ~ 127 DEG C, and the storage time is 990 ~ 1010h.High-temperature storage test is the adaptability that analog equipment operates and stores under climatic environment.
Result shows: have the base material of glue height Tg obviously can sustain thermal shock, constant temperature and humidity, high-temperature storage and do not occur the phenomenon of base material layering, plate face turning black and changing color, meet the special process of vehicle-mounted LED lamp and a series of performance test, keep original color, guaranteed quality requirement.
For a person skilled in the art, according to above technical scheme and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the claims in the present invention.
