Circuit board common four quality problems


In the increasingly fierce market competition, the circuit board manufacturers are trying to reduce costs to get a greater market share, in the pursuit of cost reduction at the same time, often ignore the quality of the circuit board. In order to let customers have a deeper understanding of this problem. Fastline will share some industry secrets to allow customers to choose circuit board suppliers more rationally.

Common circuit board quality problems are generally short circuit break, green oil foaming, green oil off, substrate layering, board warping, pad off, poor tin and aging circuit board open circuit and other problems, the fundamental reason is that the circuit board factory production process is not up to standard, backward production equipment, poor selection of raw materials, management chaos.

Reason 1: The production process is not up to standard

Circuit board production involves a series of interdisciplinary disciplines such as electroplating, chemical industry, machinery, etc. Each process must be implemented in accordance with strict production processes, and each process must be equipped with corresponding testing and laboratory equipment. The concentration of the solution in the electroplating process changes at every moment, and the current size and time of the electroplating process are different for different types of circuit boards, which will affect the quality of the circuit board. Only strict production process guidance, production according to process parameters and continuous laboratory inspection can ensure that the quality of the produced circuit board is always in a stable state.

Reason 2: Backward production equipment

The equipment is to ensure the quality of the hardware, increase the investment in the equipment, and make the equipment efficient and stable is the fundamental way to improve the quality of the circuit board. With the progress of science and technology, circuit equipment is more and more advanced, and the price is more and more expensive, resulting in some small circuit board factories do not have the ability to add more expensive equipment.

Reason 3: the choice of raw materials is cheap and poor

The quality of raw materials is the cornerstone of the quality of the circuit board, and the material itself is not enough, and the circuit made will appear foaming, delamination, cracking, board warp, and thickness inequality.

What is more hidden now is that some circuit board factories use materials that are mixed, part is genuine board material, part is side material, in order to dilute the cost, the hidden danger of doing this is that you do not know which batch of times there will be problems.

Reason 4: Management confusion

The road plate factory has many production processes and long cycle. How to achieve scientific and orderly management while reducing management costs is a difficult problem. With the progress of science and technology, especially the development of the network, it is possible to use the means of network information to manage the traditional circuit board factory. Poorly managed factories, the quality of their circuit boards will naturally fluctuate, a variety of problems emerge in an endless stream, repeated.
