When selecting circuit board components based on component packaging, the following needs to be considered: component packaging selection. Grounding methods. Virtual component packaging. Verify complete material list data. Sort. Excess gate circuit.
In the increasingly fierce market competition at present, PCB manufacturers are trying to reduce the cost, in order to achieve a larger market share, in the pursuit of reducing the cost, often ignore the quality of the circuit board.
OSP is Organic Solderability Preservatives, which refers to the coating of OSP film on the bare brass plate (double-sided/multilayer/two-layer) in place of the original protective treatment such as tin spraying on the surface of the plate.
In the process of purchasing PCBA, we need to pay urgent attention to PCBA quality control points, and adopt a professional perspective to examine whether each PCBA board meets the application requirements of electronic products.
1. Fill in the test application form（1）Report format: If SGS report needs Chinese report, you can fill in Chinese; If you need English, please fill in both English and Chinese. ITS report is filled out in English and Chinese.(2) According to the needs, en
Factors affecting PCB price: First, PCB materials used in different price diversity, second, PCB production process used in different price diversity, third, PCB itself difficulty caused by different price diversity, four, different customer requirements
Low cost is an important determinant in choosing a manufacturer, but it needs to be remembered that low cost should not come at the expense of quality, so the cost offered by the manufacturer needs to be competitive because the manufacturer has a strong r
PCBA processing on the workshop environment specific requirements: one, temperature, humidity requirements, two, ventilation capacity, three, power requirements, four, electrostatic protection requirements
This confusion has always existed in norms, standards, discussions, and documents. People think of stability tests as reliability tests, when in fact they are durability tests.
The cost of knowing product reliability is very high because you must first understand where your product will be used, how it will be used, and in what environment it will be used.
Owning the equipment and paying directly for components and labor can significantly reduce overhead costs.
Immediately afterwards, everyone, including myself, would get new phones so that we could have access to this new, wonderful technology.
