The quality of PCB products determines the market of PCB manufacturing. The quality of PCB determines the quality of products. In order to prevent defects in the manufacturing process of printed circuit boards, what machines and equipment can guarantee the quality of FASTPCBA? The following is FASTPCBA Xiaobian for everyone to talk about how to ensure the quality of machinery and equipment.
First of all, FASTPCBA has 9 detection procedures. How do the 9 inspection works play a role in controlling the quality?
1, the solder paste testing equipment (KY8080). FASTPCBA adopts online 3DSPI solder paste detector. It has the following characteristics:
1. Find out the shortage of printing quality in time. The trend of quality change was found, and the trend of control continued to spread. And then adjust it in time.
2, online AOI inspection equipment, check whether the product is wrong, reverse, solder paste printing, offset, less tin, tin, open circuit. Even tin. Pollution and other parts defect parts, offset, skew, stand, side, side, turn, fault, breakage, reverse welding spot defect tin tin less, welding, even tin, copper foil pollution and so on a series of devices, solder paste problems, so as to ensure your quality.
3. Off-line automatic AOI optical inspection equipment is the device and solder paste inspection after welding. The sensitive elements need to be treated with extra care.
4, X-RAY- welding detection, for the naked eye can not see the original solder joint detection, to avoid short circuit to flow into the next process.
5. Manual inspection of each process is strictly controlled. Printed circuit board manufacturing, from raw materials to shipping, checks the quality of the products at all levels. Jingbang is to achieve 100% factory pass rate. We understand the customer’s concern about the quality of the product in PCB manufacturing. FASTPCBA needs a continuous cooperative customer. The problem is just a single, not our original intention.
1.Snpb Hot Air Leveling craft. The Snpb Hot Air Leveling craft is a traditional PCB pad coating method. The specific craft process is immersed in the molten Snpb alloy after the PCB circuit is etched, and then slowly lifted and coated with a Snpb alloy layer under the action of hot air, which is ...
The width of the printed conductor depends on the current carrying capacity of the conductor and the allowable temperature rise. The thickness of the copper foil plated copper foil is generally 0.02 to 0.05 mm. The different widths printed conductors have different cross-sectional areas too. The ...
After the position and shape of the components on the PCB board are determined, the wiring can be performed according to the position of the components. The following are the basic requirements for the circuit board: The low frequency wires are placed close to the edge of the printed circuit boar...
