Wave solder process of wave solder RF-350B
There are many types of wave solder machines; however, the basic components and principles of these machines are the same. The basic equipment used during the process is a conveyor that moves the PCB through the different zones, a pan of solder used in the soldering process, a pump that produces the actual wave, the sprayer for the flux and the preheating pad. The solder is usually a mixture of metals. A typical leaded solder has the chemical makeup of 50% tin, 49.5% lead, and 0.5% antimony.[1] The Restriction of Hazardous Substances Directive (RoHS) has led to the elimination of leaded solder in modern manufacturing however, and lead-free alternatives are used. Both tin-silver-copper and tin-copper-nickel alloys are commonly used, with one common alloy (SN100C) being 99.25% tin, 0.7% copper, 0.05% nickel and <0.01% germanium.
Characteristic of wave solder RF-350B
★ The rosin spray device can be pulled out and disassembled for easy cleaning and maintenance.
★ Isolation spray device, flux fumes are discharged from the dedicated air duct.
★ Powerful parameter library function, various PCB process parameters can be called and operated on demand.
★ The computer + PLC control system is adopted to ensure the reliability and stability of the system.
★ The machine can be switched on and off automatically according to the date, time and temperature control parameters set by the user.
★ Self-diagnosis of system failure, automatic display of the cause of the failure, and inquiry of troubleshooting methods at any time.
★ The heating temperature adopts PID closed-loop control, and the temperature control is stable and reliable.
★ Closed-loop automatic tracking spray system, spray width and spray time are automatically adjusted, and can be set as required Advance and extend the spray time.
★ Equipped with economic operation, automatic wave generation when passing the board, which minimizes the amount of tin oxidation.
