the traditional physical plate making method is labor-intensive, time-consuming and has low precision, while the chemical rapid plate making method has a controllable precision, but the process is complicated and unfavorable to environmental protection. B
Mobile terminal with HDI board is the main point of PCB growth. The mobile terminal represented by smart phone drives HDI board higher density and thinner. PCB all to high density fine line development, HDI board is particularly prominent.
Many microelectronic devices (such as accelerometers, gyroscopes, deep ultraviolet leds, etc.) chips are very sensitive to air, moisture, dust, etc.
High frequency microwave plate forming and printed board, CNC milling is the main. But the method of milling is very different for different materials.
In the high speed signal transmission line of printed board wire, one is the high frequency signal transmission class of electronic products, the other is the high speed logic signal transmission class of electronic products.
FHow do you choose a flux?First, combined with product selection, second, according to customer requirements to choose, third, according to the equipment process selection
What is causing concern is the unpredictability of the noise itself. Typically, the noise may come from an external source or an internal source. Even the source of the noise poses more problems.
In PCB design, the hole has four functions: electrical conduction, positioning, heat dissipation, convenient board. It is also divided into pass-through holes and non-pass-through holes. Only PTH holes have pore rings, while NPTH holes have no pore rings.
Some basic testing and inspection tasks may be required to be performed on your PCB/PCBA during the manufacturing and assembly process, and it is recommended that these tests be performed, at the very least, to ensure continuity, accurate assembly, and si
Quality control in mass production and prototyping has a common set of important tasks: the need for PCB testing. The specific set of tests you need to perform in a PCBA depends on its application area, desired service conditions, and, of course, the rele
The components in the circuit module should adopt the principle of nearby concentration, and the digital circuit and the analog circuit should be separated at the same time.
