Printed circuit boards (pcbs) are generally called printed circuit boards (PCBs). Printed circuit board proofing means that a small amount of samples are produced for testing before mass production, which also answers the question of PCB proofing sold in the market. Many electronic product manufacturers will find some professional PCB proofing manufacturers to cooperate with, so what difficulties need attention in the whole process of PCB proofing?
Take a look at the total number of proofs.
Before burning in an enterprise, a batch of PCB samples are usually made for testing, and this part actually takes up part of the cost of the enterprise. If the enterprise is large in scale and produces many kinds of PCBs, the cost of PCB proofing and testing will be considerable. Therefore, in the whole process of PCB proofing, enterprises should pay close attention to the total number of proofing. At present, the pcb proofing fee is already very low. pcb factories are all priced according to the cost. Generally, single and double-board proofing is carried out on four-layer boards around 50 yuan, and it takes about 3 days for 200 yuan to produce good pcb samples.
The second is to determine the package of components.
It is a technological process of the circuit board manufacturing process to weld the integrated ic with special functions on the circuit board by electric welding and package it with a shield. During the whole process of PCB proofing, the entrusted party should pay special attention to whether the internal integrated ic and electronic components are soldered incorrectly during packaging. In order to ensure the quality of PCB proofing, only in this way can all normal verification functions be exerted, and industrial production can be carried out in the future.
The third is to conduct a comprehensive inspection of electrical equipment.
After the company’s PCB proofing, it should conduct a comprehensive electrical equipment inspection to ensure the inventory of every link and key point of the PCB. This is the practical significance of PCB proofing, and the guarantee of whether the PCB will be mass-produced afterwards and the extremely low unqualified rate. All-round inspection of electrical equipment, it is recommended that the entrusting party and the proofing party cooperate to conduct inspection to be a more careful and meticulous measurement method.
Perhaps, there are still some problems such as signal integrity and reasonable layout that must be paid attention to and handled with each other, but generally speaking, the problems that PCB proofing should pay attention to are probably the above categories. Although there are many questions about the significance of pcb proofing in the sales market, as an expert in the industry, it is the fundamental place to ensure the quality of pcb proofing and the later-stage large-scale production and manufacturing, and we must take PCB proofing seriously.
