Lead characteristics of wave soldering machines
1, adjustable width of the peaks peaks generator

Both internationally renowned brands, or domestic counterparts enterprises, the past few decades, providing the market with the full-wave soldering machine is fixed peak width. I launched the wave soldering machine, the first wave crest of realizing the smallest 120 mm width, the maximum of 350 mm width adjustable peaks. The solder wave soldering machine is saving, energy efficient and reduce pollution.

2, peaks regional nitrogen partial protection

Exposure to the air in the solder surface, the unique design of the installation of stainless steel nitrogen enclosures, under cover increases in nitrogen filling nitrogen. This low consumption of nitrogen in lower operating costs, the realization of nitrogen to protect wave soldering. At the same time reducing slag formation of solder, solder savings.
The greatly improved solder wettability and reduce the defect rate.

3, the PCB transmission speed closed-loop control

PCB transmission speed PCB and its direct impact on the stability of the welding, welding technology in Lead, the temperature welding process window smaller, welding time on the consistency is particularly important, the speed closed-loop control is to ensure consistency of welding time an important means.

4, the width of electric rail loop adjustment

Small quantities, and more varieties of electronic equipment production will require a flexible mode of production, wave soldering machine parameter adjustment convenient and flexible adaptation of the production is an indispensable condition. The closed-loop electric rail width adjustment, the only keyboard input numerical width can be so simple guide width adjustment accurate. PCB width at the same time as may be fixed in the process parameters of document, with the number of PCB in the computer automatically called.

5, patented technology, "three-phase asynchronous induction Electromagnetic Pump"

Three-phase asynchronous induction electromagnetic pump is to use three-phase power supply mutual poor 1200 phase difference in the spatial distribution and composition of their respective magnetic field, its synthetic magnetic field, the magnetic field is a forward. As a result, liquid metal solder in advance of cutting magnetic field lines, induced current, the electromagnetic force formed ahead. Three-phase asynchronous induction generator electromagnetic pump peaks without any rotating parts, no wear, maintenance-free, simple structure, but also with audio perturbation vibration wave superposition, welding capabilities and enhanced ability to crawl hole. The three-phase asynchronous induction electromagnetic pump production is a straight line thrust, without rotating liquid metal solder, tin bath surface calm, resulting in a significant reduction of slag.

6, automatic process control PCB spray

Spray PCB system can automatically detect the length, width and speed PCB transport, without artificial, the PCB can be realized fully automatic spray process.

7, the hot air preheater + IR portfolio

Hot air heating with large heat capacity, can quickly blown off the surface coating in PCB and all of the holes in excess solvent; Infrared quartz tube heating with heat capacity of small, warming fast, uniform components preheating the advantages of stability. Hot air + IR preheating portfolio, combining the advantages of both, all of the separate control, temperature uniformity can achieve very small △ T, can be better preheating effect.

8, process parameters menu management

Preheat temperature, solder temperature, rail width, the transmission speed is the closed-loop control, as well as spray process automation, all of the PCB processing parameters in the computer technology to document all storage, replacement of a PCB, only the replacement of a number of documents, we will be able to complete work Arts parameters change, it was very sexual, production equipment operating at the same time so that the process is extremely simple.


Lead reflow machine features

Hot air + far-infrared heating compound in providing the same way under the conditions of heat, smaller flow rate, can prevent small mobile devices to high-density substrates and flexible substrates can achieve high-quality welding, heating methods for composite small airflow velocity and reduce nitrogen consumption, reduced equipment operating costs, and far infrared electromagnetic waves, can be decomposed flux within the resin composition, the role of self-purification, can lower the furnace chamber, heater blower impeller and the pollution. -- Patents: ZL200420042200.5

3, a unique hot air cycle approach ω

Ω hot air cycle has proved a more uniform way of horizontal temperature distribution, the temperature distribution clear, the temperature before and after the interference temperature between small.

4, the temperature independent flux cleaner filtration and gas installations (Nitrogen Filling type)

In nitrogen-reflow machine protection, the use of temperature independent flux cleaner filtration and gas installations, can solve all in the process of returning the welding flux volatile, PCB and gaseous emissions from the full discharge of pollutants, while not causing nitrogen losses. In addition, the volatile flux-cooling will not enter the area will not be deposited in the inner cavity and PCB equipment, avoid pollution caused by the flux caused by the shutdown and yield loss.

5, Heater state of self-diagnosis function

In reflow machine control system, the design of the heater state of self-diagnosis function, can detect heater is good or bad, and promptly report to the police, to avoid the damage caused by the heater caused the temperature in welding fluctuations affect the quality of welding.

6, a smooth transmission system

Lead Solder Joint cooling, not the same as pewter solid-liquid eutectic point, but a temperature range during transport from the concussion will affect solder joint good crystallization of the smaller radius of the transport chain wheel drive transmission makes small PCB smooth, without oscillation.
