Principle:

     Click here or below photo to see all kind of our product about pulse heat soldering.

      hot bar soldering machine also named  pulse heat unit/hot bar bonding machine/reflow soldering machine/heat pressure machine/thermo-compression machine is intended to solder electric components.

    It consists of a reflow head which holds down the object and applies pressure force and the pulse heat power supply which applies the current.

    Pulse heating is an instantaneous heating method. Heating is performed only when the solder is desired to be melted.
Electric current is applied to the iron to generate heat by resistance and the solder is melted. When the solder has melted, the current will be stopped and the solder is cooled. And when the solder has hardened, the heater tip is raised.

     Because the pressure is kept applied until the solder is hardened, highly reliable joining without lifting up can be achieved.

Some welding sample:

Character:

1. IGBT inverter with 4kHz frequency.
2. Temperature closed loop control, feed back every 0.25ms.
3. Real time display temperature curve.
4. Upper and lower monitor of the temperature.
5. Easily operating. 
6. Overheat protection, overvoltage/undervoltage protection.
7. High precisely heating control system.
8. Two steps heating with upslope.
9. Ease for automation.
10. Saving power, 50% off than traditional AC soldering power.

      Guangzhou Minder-Hightech Co.,Ltd(MINDER-HIGHTECH CO.LIMITED HONGKONG ) is focused on connection(welding).

      We are comprised by a group of high educated specialists,with the leader of overseas professor, some of us have more than 20 years welding experience,our goal is to provide high performance product but low price and exceeded service.

      We care for the safety of operator, this year, we developed a safety system in spot welding industry named SOFT TOUCH system,which can prevent heavy pinch point injury.

      We are specialized in most of the connection(welding) technics,the most application we have participated in are electronic component(resistance,capacitor,inductor),chip on board,automotive electronic accessories,cell phone,IC cards,motor armature commutator etc.By material, we have engaged in connecting the Aluminum, Copper, Brass, Au(gold), Platinum, Nickel, Enameled wire, etc.

       We also provided the full IC package line; and LED producing line; Crystal oscillator producing line; as well as the wafer machining equipment.

       Our product are classified into resistance spot welding,inverter seam welding, ultrasonic wire bonding,hot bar soldering,automatic TIN soldering,stud welding, all the product are with mature latest technology,high performance,high precision,and high reliability.

       At the same time, we maintain a good relationship with the high school scientific research institution,we know the newest connection(welding) technology direction all over the world, committed to give out the best connection(welding) solution to our global customer.

       We chose the most open and industrialized city-guangzhou-to be our base head place,to ensure the efficiency and rapidly response.

       These years,we proud of our growth with the famous company such as TPT,K&S,ASM,Bosch,Miyachi,Uniteck,Avio,Apollo,LPKF etc.
