Welding distanceThe gas generated during welding will cause harm to the human body, so when using a soldering iron, the distance between the nose and the soldering iron should be more than 30cm, and 40cm is a more appropriate distance.
High-end equipment can be attached to precision shaped parts, BGA, QFN, 0201 materials. Also can be template patch, loose material hand. ▪ Sample and size batch can be produced, proofing from 800 yuan, batch 0.008 yuan/point, no start-up fee.
Red is not recommended. The red circuit board is white under the red light source of the chip camera, which cannot be programmed and is not easy for the chip machine to weld.
It has been measured that a pass hole can bring about 0.5pf of distributed capacitance, resulting in a significant increase in the delay of the circuit, and reducing the number of pass holes can significantly improve the speed
Cross-segmentation may not be relevant for low-speed signals, but in high-speed digital signal systems, high-speed signals take the reference plane as the return path, that is, the return path. When the reference plane is incomplete, he following adverse
high temperature performance is good: most of today's SMT circuit boards need to install components on both sides. Therefore, the PCB machined by SMT needs to be able to withstand two reflow soldering temperatures. At present, lead-free welding is widely
small aperture: most of the metallized holes in SMT are not used to insert component pins, and are no longer welded in the metallized holes
Control welding temperature: Reasonable control of welding temperature can avoid the formation of bubbles and voids below the solder joint. If the welding temperature is too high, the material below the solder joint will produce gas, resulting in virtual
Accumulated service for thousands of electronic enterprises, involving many types of automotive equipment and industrial control motherboard SMT processing services, products are often exported to Europe and the United States, quality can be affirmed by n
To mitigate this impact, manufacturers often take various measures, such as placing components in cooler areas or using components that are more resistant to high temperatures
Control welding temperature and time: In the welding process of the PCB board, the welding temperature and time should be controlled to avoid excessive heating or heating time is too long, resulting in bending or warping of the plate
Manual cleaning method is one of the simplest and most primitive methods to remove excess tin residue. It is mainly manually operated, using hand tools (such as scissors, scrapers, spray guns, etc.) to clean up excess tin residue. The advantage of this me
