The most reliable PCB & PCBA custom service factory.
This is not only the PCB design industry, but also other industries. Low prices are not the magic weapon to win in market competition, but quality is particularly important. The PCB design industry is more prominent in this aspect. Let me give you an example to briefly explain: When the general customer conducts PCB design or reverse development, the investment cost is often relatively large. If the cost of PCB design is only a small amount On the contrary, the accuracy of the copied board files affects the success or failure of the entire project. It occupies a decisive factor in reliability, safety, and manufacturability. Therefore, many customers would rather pay a high price to find a high-quality PCB design company for design. Will not favor low prices.
If the success of the project is defined by 100%, the importance of PCB design does account for 80%, so the quality of PCB design is particularly important.
The importance of PCB design
With the advent of the era of high-speed design, the quality of PCB design (circuit board design) directly determines the quality, cycle, and cost of product development. It has become a key link in the product design chain. We believe that: "the best design" = "design quality" + "cost control",
a good PCB design not only guarantees good board performance, but also can maximize the reduction of PCB production costs for customers with the simplest process design. The hardware engineer provides convenient operation during debugging. This not only makes the product or design plan have a professional guarantee. At the same time, the timely launch of the product and the reduction in cost have also won the opportunity for our company and quickly occupied the market.
Points to note in PCB anti-deformation design
1. What is PCB deformation?
The deformation of PCB, also known as warpage, has a great influence on welding and use. Especially for communication products, single boards are installed in sub-boxes, with standard spacing between boards. With the narrowing of the panels, the gap between adjacent plug-in components becomes smaller and smaller. If the PCB is bent, The process of electronic processing will affect the plugging and unplugging, and will touch the components. On the other hand, PCB deformation has a great influence on the reliability of BGA components. Therefore, it is very important to control the deformation of the PCB during and after the soldering process.
2. PCB anti-deformation design requirements
(1) The degree of PCB deformation is directly related to its size and thickness. Generally, the aspect ratio is less than or equal to 2, and the width to thickness ratio is less than or equal to 150.
(2) Multilayer rigid PCB is composed of copper foil, prepreg and core board. In order to reduce the deformation after pressing, the laminated structure of the PCB should meet the symmetrical design requirements, that is, the thickness of the copper foil, the type and thickness of the medium, the graphic distribution items (circuit layer, plane layer), and the pressing property relative to the thickness of the PCB The center line of the direction is symmetrical.
(3) For large-size PCBs, anti-deformation stiffeners or lining boards (also called fire-proof boards) should be designed. This is a mechanical reinforcement method.
(4) For partially installed structural parts that are likely to cause PCB deformation, such as CPU card holders, a backing plate that prevents PCB deformation should be designed.
Why choose PCB outsourcing design company
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, focus on what it does best, and other related peripherals. Partially outsourced to partners. Such parallel work is conducive to the timely launch of products, and can also provide professional guarantees for products or design schemes.
