Selective soldering is the process in which specific components are soldered to PCBs (Printed Circuit Boards) and modules. The components could not be treated in a reflow oven in a traditional surface mount technology process due to thermal shock and damage. Process of flux appliance as a first step of the selective soldering process sets the baseline for achieving high-quality and robustness of the soldered joints.
Selective soldering, when compared to other soldering processes, is considered demanding as it has certain pre-requirements like a specified flux quantity, a preheating time, etc. But precise and accurate work done by selective soldering machine China can result in zero-fault production.
The compact machine design with small footprint guarantees reproducible soldering results and hence offers an economical alternative to conventional hand soldering procedures. Highest process reliability s ensured with many automatic process control features like process visualization, offline teach program VIP or fiducial recognition with PCB alignment.
Let’s have a look at some of the best selective soldering machines China by Sassino:
Inline Selective Soldering Machine FLEX-I2
Machine Operation Mechanism: The PCB will be moved in the machine with stainless steel wheels conveyor system. It will be then stopped by stopper and side clamped by rear clamper cylinder. The spray fluxer will then start to work under the setting program, and after that, the same table will move x,y,z1,z2 to move different solder pot under PCB for selective soldering. The top pre-heater is on during the entire process to help maintain the PCB’s temperature.
Features:
- XY servo table for solder station.
- Servo axis Z1 for solder pot 1.
- Servo axis Z2 for solder pot 2.
- Optional electro-magnetic pump.
- Top preheating zone.
- Standard equipped with wave height calibration.
- Drop jet fluxer.
Details:
- Spray Flux: Standard equipped with drop jet valve, which can meet a diameter of 2mm flux dot dimension.
- Selecting Soldering Pot: 100% lead-free titanium soldering pot is standard equipped with a mechanical pump and easy for maintenance.
- Live Camera: With Sod-ProcMoni, operators can see the soldering process in real-time.
- Pre-heating: Pre-TPRE is standard equipped with upper pre-heating zone to reduce the temperature drop on PCB during soldering.
- Solder Nozzle: Sod-WetNoz is equipped with a wet nozzle for customer’s universal application.
Offline Selective Soldering Machine Ant-I1
Machine Operation Mechanism: PCB is moved by X/Y table with servo motor, drop jet flux is moved in Z with air-cylinder, and a solder pot is moved in Z with servo motor.
