PCB manufacturing has conventional requirements and unconventional requirements. The PCB circuit boards of conventional demand are large in quantity and affordable, and are favored by customers. So, what are the general requirements for PCB manufacturing? 1. Meet: PCB processing technology requirements. 2. The surface treatment has strong anti-oxidation ability. 3. It can directly point out…
When customers customize PCB products, they will produce more in quantity to prepare for they pcb projects. Over time, the PCB board will expire. So, what are the hazards of using expired PCB circuit boards? 1. Expired PCB fabrication may cause oxidation of surface pads Oxidation of the solder pad will cause poor soldering, which…
In addition to the basic FR-4 materials in PCB production, some customers also indicate that high TG materials are to be used in the materials, so why use high TG materials in PCB production? The full name of TG used in pcb manufacturing is glasstransition temperature, which stands for glass transition temperature. The circuit board…
With the development of science and technology, LED technology is also constantly developing, bringing all kinds of convenience to our lives, providing us with all kinds of life information, and benefiting us human beings. If you want the LED switching power supply to have the best PCB component layout, then before proceeding with component layout…
PCBA board processing belongs to high-precision manufacturing and must comply with relevant actual operating rules. So, what are the precautions for PCBA board processing? 1. During electronic pcba processing, the surface to be soldered cannot be taken with bare hands, because the grease secreted by human hands will reduce solderability and easily lead to soldering…
In daily life, the multi-layer PCB circuit board is currently the most widely used circuit board type, and it can have such an important proportion, which must benefit from the many advantages of the multi-layer PCB board. Advantages of multi-layer circuit boards: 1. High assembly density, small size and light weight, meeting the needs of…
The production process of PCB board is relatively complex, and it involves a wide range of processes, from simple mechanical processing to complex mechanical processing, common chemical reactions, photochemical, electrochemical, thermochemical and other processes, computer-aided design CAM, and many other aspects of knowledge. Because the production process is a non-continuous assembly line form, any problem…
The pad is the basic unit of PCB surface mount assembly. So, do you know what the PCB Smt manufacturing process requires for pads? 1. Test points should be added to the pads where the two ends of the chip components are not connected to the plug-in components. The diameter of the test points is…
In modern, all electronic products are inseparable from pcb board; different circuit boards have different applications, and their corresponding quality is also different. The PCB Manufacturing Classified by demand: ■ Enterprise-level user needs. Enterprise-level user needs are mainly concentrated in the fields of communication equipment, industrial control medical and aerospace. Related PCB products often have…
What file should be provided when making PCB samples? The PCB manufacturer cannot work directly during the manufacturing process, nor can the PCB layout file be directly converted into the manufacturing instructions for the automated equipment. Most manufacturers will require some or all of the following PCB manufacturing documents: 1. Gerber, BOM and site-specific documents…
