1 Neglect of cooperation with PCB manufacturers
It is a common misconception that many engineers think that it is enough to provide design files to the manufacturer before manufacturing begins. In fact, it is best to share it with the manufacturer when designing the first draft of the PCB layout. They will review the PCB design based on their rich manufacturing experience, and find problems that you can’t find, so as to ensure the manufacturability of the design.
2 too close to the edge
Components should not be too close to the edge of the circuit board, and an appropriate distance needs to be kept, otherwise the components are easily broken due to being too close to the edge. And this problem, experienced manufacturers can often find out when they get the design files, and ask engineers to make modifications, such as routing around the edge to solve hidden dangers.
3 Ignore the verification of PCB layout design
When you spend a lot of time and effort to complete the PCB design, but you can’t wait to get into production, then you are doing it wrong. The verification of PCB design must not be ignored, otherwise it will bring a lot of trouble. Imagine waiting until the PCB production has started to find out the problem, it will waste a lot of time and bring greater economic losses. Therefore, we need to verify the design multiple times to ensure that it is correct before it can be put into production. We recommend performing Electrical Rule Checking (ERC) and Design Rule Checking, these two systems help us verify that designs meet common manufacturing requirements, high-speed electrical requirements, etc., and identify potential design issues early and correct them quickly.
4 Complicates PCB design
Unless necessary, some complicated designs should be avoided as much as possible, otherwise it will take extra time and cost to manufacture. For example, undersized parts can complicate production. If the circuit board has enough space to accommodate larger components, large-size components should be selected, which is more in line with the manufacturability of the product. In short, spending more time in the design stage, making the layout simpler and meeting the functional requirements, the effect will be better, which is conducive to improving production speed and quality.
We have a global parts supplier database, supply various quantities of parts and various PCB related products, abundant parts procurement of various components and fast logistics suppliers to achieve fast global delivery of PCBA.
