Therefore, good equipment maintenance is the key to ensuring the SMT processing. Let&#39...

Nowadays, semiconductors are becoming more and more integrated. Many appliances also have system-level chips that are readily available. Many out-of-the-box development boards are powerful, but lots of electronic products still require customized PCBs. In one-off development, even an ordinary PCB can play an important ...

Over the years, new technologies have been introduced in vehicle manufacturing. These innovations have brought significant changes to the industry and promoted the development. Among them, automotive electronic printed circuit boards (PCB) are popular in vehicles. They play an important role in providing mechanical sup...

When testing printed circuit boards, it is time to pay attention to some details in order to ensure product quality. When doing the tests, there are 9 tips that you should know. 1. It's strictly forbidden to use grounded test equipment to touch the live TV, audio, video and other equipment on the bottom board to te...

Usually, the quotation for printed circuit boards is given by the factory. With the continuous advancement of Internet technology, many factories now have their own online quotation systems for PCB. There are some factors that affect cost and price. 1. PCB size (dimensions) Let's talk about the size of printed circ...

In PCB design, layout is an important step to complete product design. The previous preparatory work is done for it. In the whole PCB, the design process of wiring is the most limited. The skill is the most detailed, and the workload is the largest. PCB layout includes single-sided wiring, double-sided wiring and multi...

1. Correctness This is the most basic and crucial requirement for printed circuit board design. We should connect the relationship of the electrical schematic diagram and avoid the two simple and fatal mistakes of "short circuit" and "open circuit". This basic requirement is not easy to achieve in m...

Nowadays, PCBA manufacturing is a mature processing method, which is mainly used for the high integration of electronic equipment processing. However, before the manufacturing, we must hold a pre-production meeting to plan everything. It is necessary to do well in the procurement and inspection of pcba electronic compo...

For PCBA, performance tests after manufacturing is necessary. According to the actual environment and purpose of the product, the tests are generally divided into withstand voltage test, insulation test, salt spray test, impedance test, vibration test, high temperature and high humidity test, welding strength thrust te...

Drawing design is important for PCB, so how to check if it doesn't goes wrong? After the circuit board wiring is settled, check the PCB for rules to ensure that the circuit board meets the design requirements. All nets should be connected correctly. Commonly used inspection items in design rules are as follows: Che...

PCB and PCBA, as important components in the electronics industry, play key roles in electrical interconnection and circuit. The printed circuit board provides the fixing and electrical connection of electronic components. And PCBA, as the manufacturing process of the printed circuit board, completes the assembly and w...

PCB surface finishing is used for 2 things. First is to protect the exposed copper circuitry and second is to ensure solderability. The difference in material used will affect the price, shelf life, reliability and assembly processing. Types of Surface Finishing 1. HASL (Hot air solder leveling) – Leaded and Lead free...
