In 1950, the first panel appeared. The single-panel material was made of paper phenolic substrate. The simple understanding of the double panel is that there are wiring on both sides. This makes it better. The multi-panel refers to more than 2 layers. Price, please see below The history of single-sided boards: The single-sided printed circuit [...]
The arrival of the 5G era has put forward higher requirements for the R&D, production and management capabilities of the majority of circuit board companies. Enterprises must provide more cost-effective products to the market at a faster speed, and it is very important to improve product management traceability. A ring. Marking characters, patterns, one-dimensional codes, [...]
Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connections for electronic components. It has been developed for more than 100 years; its design is mainly layout design; the main advantage of using the circuit board is that it greatly reduces wiring and assembly errors, and improves [...]
Water-based cleaning process for circuit boards, how to choose the right cleaning equipment? - Heming Technology Key words: circuit board cleaning, PCB component cleaning, water-based cleaning technology, spray cleaning machine, ultrasonic cleaning machine The SMT/DIP electronic assembly cleaning requirements are based on the application, customer, rework and overall steps in the process, and are required [...]
Key words: circuit board cleaning, water-based cleaning, thermal oxidation, rosin, PCB component board In the electronic process technology, PCBA (circuit board or circuit board) often whitish after cleaning, and the white mark is scattered around the solder joints, which seriously affects the appearance acceptance and brings quality hazards. White Residue Risk Factor: When considering [...]
In the initial stage of debugging and the maintenance stage of the circuit board, the replacement and replacement of components are encountered. Disassembling the components is a technically hard work. If you pay attention to it, it will cause damage to the disassembled components. Even damaged the pad. The electronic components are sensitive to temperature. [...]
In the SMT electronics manufacturing process, PCBA or circuit board / circuit board water-based cleaning process, how do we balance water-based cleaning and material compatibility issues? Water-based cleaning needs to be controlled from the cleaning process. The requirements and material factors that affect the cleaning process include circuit density, component height, flux residual composition, reflow [...]
A beautiful and practical table lamp can be called a piece of art on a desk. Looking at the beautiful and beautiful table lamp on the desk may add some reading pleasure. So what is the working principle of the touch switch lamp? Two-button touch dimming circuit board working principle: One or two button touch [...]
First of all, let's first introduce what is Shen Jin? The copper on the circuit board is mainly copper. The brazing joints are easily oxidized in the air. This causes electrical conductivity, that is, poor tin or poor contact, which reduces the performance of the board. Therefore, the brazing points need to be surface treated. [...]
Circuit board proofing (PCB proofing) refers to the trial production of printed circuit boards before mass production. The main application is the process of small-scale trial production by the electronics engineer after designing the circuit and completing the drawing of the PCB to the circuit board factory. Proof for board (PCB proofing). Circuit board proofing [...]
