pbc circuit board design software-FS Technology
Abstract: Design a printed circuit board based on a schematic circuit to perform the functions required by the circuit manufacturer.Print design design refers to the circuit design, which must take into account the external design of the joint, the detailed design of the internal electrical components, and the detailed design of the metal joints and holes. What are the PCB circuit board design software? FS Technology will introduce you the mainstream pbc circuit board design software
The most popular circuit board design software in China
Protel, protel 99se, protel DXP, Altium are widely used in China. All of this software is developed and continuously developed by the company; the current version, Altium Design 15, is straightforward and can be used to easily create FS Tech PCB boards. But these softwares are not suitable for making hard PCBs.

Design better circuit board design software
Cadence SPB software Cadence SPB is Cadence software, the latest version is Cadence SPB 16.5; ORCAD design program is a global standard, and is also the most used circuit board design software by FS Technology; PCB design and simulation are more complete, and the use is much more complicated than Protel. The requirements and features are complex; but the rules are designed for the design, so the design is better, less work, and significantly stronger than the prototype.

Circuit board design software that few people use
Metor Boards and EEs, which only work on BOARDSTATION UNIX systems, are not designed for PCs, so they are rarely used; the current MentorEE version is Mentor EE 7.9, Cadence SPB is the same standard as PCB design software, and in some respects is better than Cadence Poor SPB. FS Technology has hardly used this type of board design software

The most popular circuit board design software in Europe and America
Eagle Layout is the most widely used PCB design software in Europe. Most of the PCB design software mentioned above are the most widely used, with Cadence SPB and Mentorai kings being the most ideal. If you are new to PCB design, FS Technology believes that Cadencespb is better, it can give manufacturers a good design experience and ensure good design quality. -
Basic knowledge of PCB board making-FS Technology
Therefore, the copper surface of the PCB used for soldering must be protected by a solderability protective layer or a solderability barrier layer in order to reduce or avoid failure problems.PCB concept
PCB can be said to be common or uncommon in our lives. It is an important electronic component and a support for electronic components. All electronic products in our lives contain PCB boards. The full name of PCB is Printed Circuit Board, which is called "printed" circuit board because it is made by electronic printing.
The role and function of PCB in various electronic devices
1. Pad: Provide mechanical support for fixing and assembling various electronic components such as integrated circuits.
2. Wires: wires used to connect various electronic components, which can help circuit boards achieve wiring and electrical connection (signal transmission) or electrical insulation between components. Provide the required electrical characteristics.
3. Green oil and silk screen: Provide solder mask graphics for automatic assembly, and provide identification characters and graphics for component insertion, inspection, and maintenance.
Development history of PCB technology
Since the advent of PCB, if we look at the development of PCB assembly technology, FS Technology has divided it into three stages
THT-Through Hole Technology Stage
The role of metallized holes:
(1). Electrical interconnection---signal transmission
Literally, the electrical appliances are directly connected or indirectly connected through transformers and the like
(2). Supporting components---pin size limits the reduction of through hole size
a. Rigidity of the pins
Pin, also called pin. It is the wiring from the internal circuit of the integrated circuit (chip) to the peripheral circuit, and all the pins constitute the interface of this chip. A segment of the end of the lead, which is formed by soldering to form a solder joint with the pad on the printed board. Pin can be divided into bottom, toe, side and other parts.
b. Requirements for automated instrumentation
There are three ways to increase density
(1) Under the regulations (aperture ≥ 0.8mm) to reduce the size of the device hole, why is there a regulation? This is because of the rigidity of the component Pin pins and the limitation of the insertion precision.
(2) Control line width/spacing: 0.3mm—0.2mm—0.15mm—0.1mm
(3) Increase the number of layers of the circuit board: the better the technology, the more layers can be added, FS technology can achieve all the layers, 64 layers - 12 layers - 10 layers - 8 layers - 4 layers - double-sided - single noodle,
The perfect circuit board made by FS Technology
SMT-Surface Mount Technology Stage PCB
1. The role of the via hole: it only plays the role of electrical interconnection, the aperture can be as small as possible, and the hole can also be plugged.
2. The main way to increase the density
①. The size of the via hole decreases sharply: 0.8mm—0.5mm—0.4mm—0.3mm—0.25mm
②. The structure of the via has undergone essential changes...
