Suspected that the transmitter circuit board has malfunctioned and can be temporarily replaced. How to handle the issue of overweight containers for printed circuit board assembly?
The internal insulation layer of a new type of printed circuit board assembly is a problem with the thickness of the insulation layer that has passed the testing and inspection on an SMT machine.
High speed SMT design software is used to solve the problem that the reflow soldering temperature curve of printed circuit board assembly is too fast and cannot reach the temperature that cannot reach the reflow soldering temperature. The boards that cannot reach the reflow soldering temperature are also prone to the TG value, which causes the boards to need rework.
Using lead-free solder paste or lead-free solder paste, customers need to design their own wave soldering machine, which is difficult to maintain and cannot be used.
Wave soldering machine is a relatively new product in the electronics industry, and there are many benefits to using wave soldering machine. Therefore, it is necessary to appropriately reduce the use space of wave soldering when using it.
Choose the appropriate width, and if you need to choose the appropriate peak height, you need to consider reducing the number of peak soldering.
Key points: Check whether the power supply voltage is normal; Pay attention to whether there are any issues with the fan, power supply voltage, and other equipment of the machine; Pay attention to whether there is enough space for placement and placement; Based on whether to perform small-scale decoration, pay attention to whether there are any debris on the circuit board; Do not pollute the gas source when familiar with it; Pay attention to whether the heat dissipation during baking is abnormal; Pay attention to gentle drying and heat dissipation.
When applying the film, it must be hot applied at the bottom and avoid incorrect or missed application; If there is no mistake in pasting, then the bottom heat stick should be placed on the bottom heat stick, and the temperature at the bottom must not be lower than 25 ° C. It is best to stick it only in a hot place, and due to the influence of the heat stick, a 05mm glass wire must be pasted between the upper and lower lines.
Place a 05mm glass wire under the hot paste and take it out to see. Its function is to attach it to the components on the PCB board, and it can be attached to the glass wire inside the entire component. It also has anti-static function, making it easy for manufacturers to use.

In addition, the most direct method is to drill holes on the board that needs to be inserted before the plug-in, or to weld the plug-in online.
Xinchang Electronic Technology specializes in Wuhan SMT mounting, PCB circuit board welding, PCB circuit board mounting, etc., with quality assurance!
If you are a senior repairman, then your repair workbench is a versatile worker, and each of our equipment has undergone strict maintenance. Today, we will share with you the maintenance methods and processes of the SMT mounting machine!

Disassemble the patch components and carefully inspect them to ensure that their appearance is intact and free from looseness. 2. Check if there is anyone on the workbench and if the equipment is qualified without any abnormalities. 3. Check if the power supply is working properly and all parts are normal. 4. Check the electronic equipment and provide proof of damage to the amplifier. 5. Wave soldering 1. Wave soldering furnace failure does not stop, and repair can be attempted. 2. To judge equipment failure, use AUTOSAN's flux connection to check whether the and3 end is normal, and then perform wave soldering maintenance again.
