We are a professional manufacturer of PCB circuit board. PCB processing, SMT SMT chip welding, and plug-in assembly are carried out in our factory. Make board: single side, double side, four-layer board—proofing, batch, supporting file types: PCB, PCBDOC, Gerber, etc.
Plate: FR-4 Thickness: 0.5-3.0mm The solder resists: green, blue, red, black, white. Process: ordinary tin spray, pure tin, OSP, chemical gold Molding: CNC milling, V-CUT, die stamping SMT SMT: Yamaha Mounter has high precision and high efficiency, and it is not afraid of 1206080506030402. Constant temperature 16-way reflow soldering effect of satisfying customers! Dip plug-in welding: each component is stable, proper, and proper, without bias and leakage. It is full of front-line workers’ enthusiasm—manual welding, tin dipping welding, clean and neat. Packaging: the welded finished products are inspected to be qualified, packed independently, and packaged with recyclable cartons for external use, to prevent damage caused by long-distance and prevent customers from receiving them; You determine satisfaction, if you are satisfied with our service and products, please give us 5 points of praise, after all, with your support, we will go better and more stable, thank you for your evaluation and print, we work together to do better ourselves!
Common design mistakes of quick turn PCB prototype assembly
Our company can’t make a square hole
The orifice cap oil is a standard industrial-grade design requirement for mass production. We default to cap oil (no matter if your document is not equipped with Gerber). If you need to change it, please make a separate explanation. The via hole in the Gordon document is produced according to the drawing document, even if there is a via description, it is invalid. Please know!
MPlayer does not spray tin: when designing, please pay attention to it. It looks like it is the same as the pad. In fact, it will not be made into a pad, and there will be wiring at both the top and bottom layers. Please pay attention!
As for the mistakes caused by the design being locked, we often find that the mounting holes in the PCB files designed by customers are locked (if you click the figure to view the properties, the check after locked represents locking). In this case, we must find the unlocking one by one to output effective graphics. For example, if you look at it all over, it will cause leakage or slot, so in order to avoid leakage and slot, please do not lock the design We will not be responsible for the leakage caused by the leakage.
The mechanical layer and keep out layer are wet, resulting in full processing. Generally, the mechanical layer is used for shape development, and keep out layer is a prohibited wiring layer. We usually make the appearance and installation holes according to the mechanical layer. If there is no mechanical layer, only the keep-out layer is used to make the shape and installation hole. If the design does not conform to our requirements, please modify the design to indicate the details in the order details Let’s go. There are also some design isolation slots that are neither in the mechanical layer nor in the keep-out layer. It is very difficult for us to find that more than 90% of them will be missed. Please design engineering to avoid this practice. We are not responsible for the problems caused by mixing
If there is a problem in the design, don’t say that it was right last time, but it must be right this time. In other words, we have done two things at the same time, one is right and the other is wrong. Many times, our engineers will help you to correct, but the wrong design will make mistakes one day. We must improve and use the problem of perfect standard design.
