At present, many PCB proofing companies have established relatively complete test methods, test standards, various test equipment and instruments to detect and identify the qualification and service life of Allegro proofing products. PCB products are not only convenient for standardized assembly of various components, but also for automatic and large-scale mass production. Therefore, PCB proofing with reliable quality has outstanding advantages. So what skills do you need to master to ensure that the PCB proofing work is more outstanding?
1、 Board geometry and current
Most people who are engaged in electronic design know that, just like the river along the river, electronics may encounter throat points and bottlenecks. PCB designers occasionally produce similar electrical throat points in their PCB design. For example: use a 90 degree bend where two quick 45s angles can be used to form an angle; The bending degree is greater than 90 degrees, forming a zigzag shape.
2、 Resolve fragmentation issues
Fragmentation is a manufacturing problem that can be better managed through correct circuit board design. When designing PCB layout, try to avoid leaving very narrow copper area. This area is usually caused when copper is deposited at the intersection of wire and pad gap. If you set the width of the copper strip to exceed the value allowed by the manufacturer, your design should have no such problems.
3、 Follow DRC
Most design teams will establish a set of design rules to: standardize the bare board construction cost and improve the yield; Assemble, inspect and test as consistently as possible.
4、 Know the OEM you are using
A good OEM will provide some helpful help and suggestions before you place an order, including how to improve your design to reduce design iterations, reduce problems encountered during debugging on the test bench, and improve the yield of the circuit board.
Combining the above four aspects to measure the printed circuit board produced by proofing, the PCB proofing can be done more carefully. At present, there are tens of thousands of PCB proofing manufacturers in the market. Xiaobian suggests that users should polish their eyes during the selection process, and select manufacturers on the basis of a certain understanding of PCB proofing, so as to prevent being cheated.
