Nowadays, there are many equipments and instruments whose craftsmanship is very precise. The craftsmanship of this type of precision equipments and instruments is very complicated, and the required professional technical requirements are very high. After all, as long as there is a slight error, it can lead to the entire component. Neither can be used. PCB patching is such a job, and the technology that engineers who perform PCB patching should have should be very solid. Then let me introduce to you what PCB patching is like?
At this stage, many companies still use hardware engineers to carry out PCB design and program development. In addition to these, hardware engineers need to do more professional work,
which will inevitably extend the time to market for products. And now with the development of high-speed digital electronic technology, the requirements for high-speed PCB design are also higher: signal integrity simulation analysis, timing analysis, single board and complete machine EMC/EMI, etc.; and the design density of single board is also increasing. Large, but also to master the relevant design software.
The serialization of these tasks greatly extends the time to market for product development. In the fierce market competition, core competitiveness is an important part of a company’s survival. The key to a company’s success is to strengthen its core competitiveness and focus on what it has done well and other related peripheral parts. Outsource to partners. Such parallel work is conducive to the timely launch of products, and can also provide professional guarantees for products or design schemes.

So outsourcing PCB design, what information does the outsourcing company need to start PCB design:
1. Schematic diagram of the confirmed version of the software version
Why is the software version required? Because PCB design engineers need to refer to the schematic diagram for modular layout during the design process; the current size can be obtained from the schematic diagram, so after the PCB designer has the schematic diagram, it can be even more powerful. The quality of PCB design has been greatly improved.
2. Component packaging (specifications)
Component packaging refers to the actual size and shape of the components in the PCB. Because each company has different package library specifications, the design company will ask to provide package library files before the start of the design. If it is a newly added device without packaging, provide the correct datasheet, and the design company can create it according to the datasheet Package.
3. Board structure diagram
The so-called board structure diagram is also the board frame size diagram. With this size diagram, the design company’s engineers can layout and route according to the board size. Of course, it also involves the location of the fixed components, so before the design starts, you need to inform the design company of those The fixed device has facilitated the layout of the design company. The size of the board frame is one of the factors that have a great influence on the design. The change of the board frame will cause a very large amount of PCB design changes. Therefore, before the design starts, try not to modify the structure. The workload of PCB changes caused by the design company will depend on the situation. Charge for changes.
4. Design requirements
Design requirements refer to the basic feature requirements and special design requirements of the board design, such as the number of PCB layers, to small line width apertures, and special routing rules. With these requirements, the designer considers these factors at the beginning of the design. The design can be completed more smoothly in the later stage.
