PCB design: Analysis of quality problems in electroplating and etching of printed circuit boards
The lines form "copper roots" on both sides after etching, and the copper roots narrow the line spacing, resulting in printed circuit boards that do not meet the requirements of Party A, and may even be rejected.
PCB is connected to the outside world
There is a little bit of short circuiting between digital and analog, but note that there is only one connection point. There are also differences on the PCB, which is determined by the system design.
Pcb welding principle and welding tools
The molten solder diffuses along the surface of the welds with the help of capillary suction, forming the infiltration of solder and welds, firmly bonding the components and the printing board, and has good electrical conductivity.
PCB layout
With Spectre circuit simulation platform, WillSemi maintains design integrity throughout the design cycle, increasing simulation throughput and improving productivity.
Interface between PCB and the outside world
The high frequency circuit should be grounded in series at multiple points, the ground should be short and rented, and the high frequency element should be surrounded by a large area of grid foil as far as possible.
Purpose of PCB galvanizing
Their positioning is clear and their customer groups are very stable. Generally, they do not accept factory orders, because they are not short of orders at all.
Ningbo pcb proofing factory
It is made of materials, generally using epoxy glass cloth coated copper foil plate to make, its main performance requirements have very high communication electronics, the production process is very, the process generally includes plugging method, proces
The characteristics of PCB galvanizing are summarized as follows
In the semiconductor electronics industry, if you want to become a qualified electronic, in addition to understanding the basic knowledge, but also know the key points of circuit protection device selection.
Hand-made PCB
The molten solder diffuses along the surface of the welds with the help of capillary suction, forming the infiltration of solder and welds, firmly bonding the components and the printing board, and has good electrical conductivity.
pcb flux has inorganic series
Manual welding is a very practical skill, after understanding the general method, to practice more; More practice, can have better welding quality.
PCB proofing factory services
Fanyi has a series of features such as independent PCB online ordering, CRM management system, online self-quotation, self-ordering, online payment, online query of production schedule, express tracking and so on. Fanyi PCB proofing is a possible choice!
