As long as you use the product normally according to the requirements, if there are quality issues within 1 year, share common knowledge about rigid-flex board products.
The soft and hard bonding board, wire, power supply, prefabricated materials, and PP materials of this source core are processed strictly according to the requirements before leaving the factory.
According to the needs of different industries, introduce and produce technologies and concepts to ensure the quality of soft and hard combination board products.

Strictly verify the actual product, strictly follow the processing flow and operation instructions during the operation process, and strictly control quality!
According to the requirements of customized sampling and batch production, the quantity of samples shall be determined according to the corresponding sample requirements or specifications, and complete samples and special process PCB boards shall be issued.
The inspection of finished boards, including the detection of metallized holes and appearance points, is relatively simple, but the following four items need to be tested: 1. The number of layers of PCB boards (the copper thickness inside the double-sided board is generally greater than 1OZ),
For the production of multi layer boards, high standard testing equipment is required. Due to the large number of layers of multi layer boards, the testing equipment in the general laboratory is insufficient for testing. The disadvantage is that there are a large number of testing instruments and processes, and the testing equipment in the general laboratory is insufficient for testing. PCB backplane exported from Wuhu City.
When GBT8481 experiences a short circuit, GBT only experiences a short circuit fault once and does not disappear. The reasons for this phenomenon may be: (1) the device is not installed in place, and the connection points are installed horizontally and fixed; (2) The zero sequence current voltage and voltage difference increase; (3) MCU output signal short circuit, current increase; (4) Photoelectric isolation device failure; (5) Abnormal zero sequence voltage; (6) Mismatching of voltage differences at different frequencies; (7) Logically, it outputs at high frequencies; (8) Simulate the generation of voltage for triangles or triangles; (9) Abnormal phase sequence; (10) The coil of the pulse transformer is damaged; (11) The connection line is broken.
Short circuit to the circuit, inter turn short circuit, and no major part short circuit. The cause of the occurrence, such as faults (including load short circuits), long-term use (or continuous operation) can cause insulation electricity.
When you see traces or traces of printed circuit boards, are there any small integrated ICs or traces of gold fingers? When there are black traces, are there any traces of plugging or unplugging integrated IC interfaces.
Due to excessive current, an integrated IC with an approximate capacitance may show signs of burning out. This situation can generally be replaced by an infrared camera, and Taiwanese friends can inspect it.
For integrated ICs without a power supply, due to their high output power, they usually cannot be directly connected to the output terminal (such as the LED power supply on the computer motherboard). This requires a high leakage current LED power supply to dissipate its heat source. LED lights also often use an EMI filter added to the power supply because of the non-linear inductance of the external working voltage compared to the power supply. If the effective inductance is too large, it will reduce the THD of the total output power when the load increases. If the effective inductance is too large, If the inductance is too small, although it may cause interference from the switching power supply, it will still make the LED light unable to be felt and illuminate the LED light.
