Currently, lead-free PCB assembly is becoming increasingly common. How can we produce qualified lead-free PCBs? The following are the things we need to pay close attention to:
PTH wave soldering time
For PTH assembly, the welding time should be controlled as accurately as possible. Generally speaking, the process from heating the solder joint to melting and filling the solder joint should be completed within a few seconds. If the time is too long, the flux on the solder joint will completely evaporate and eventually lose its soldering effect, or if the temperature of the solder joint cannot reach the soldering temperature due to too short a time, the solder cannot be fully melted, and there is only a small amount of soldering on the solder joint, causing poor contact, this is called virtual soldering phenomenon.
Dosage of solder and flux
In addition, attention should be paid to the amount of solder and flux used, as too much or too little can affect the quality of the soldering. In addition, during the welding process, be careful not to touch the solder joints, especially when the solder on the solder joints has not completely solidified. Do not move the welding equipment and wire on the solder joints, otherwise the solder joints will deform and virtual welding will occur. Only by understanding its welding procedures can it fully exert its best effect.
Temperature of soldering iron tip during manual welding
For manual soldering, the temperature of the soldering iron tip is very important because different soldering iron tips placed on rosin blocks/flux at different temperatures will produce different phenomena. Therefore, it is necessary to keep it at the appropriate temperature, usually the temperature at which rosin/flux melts quickly and does not smoke is the most suitable.
All materials must be lead-free
To obtain lead-free PCB assembly services, we must ensure that all materials are lead-free, including all electronic components and PCBs. When purchasing components, you need to request suppliers to provide parts that comply with RoHS standards. In addition, it is necessary to order lead-free PCBs.
Stable personnel
Additionally, personnel must be stable. Try to stabilize frontline employees, technicians, and process engineers as much as possible. The positions of several key personnel must be stable, and negotiations with clients should be done after discussion. Efforts should be made to operate according to the contract in order to achieve long-term cooperation.
