PCB special purpose equipment introduction

  The precise PCB special purpose equipment mainly uses in the line board patching, can give the production line board the factory to provide very big convenient, reduces the abandonment board, decreases the cost the very good tool.Below on aspects and so on principle of work makes the subtotal

1. The machine structure

mainly is composed by following several parts:

    The main engine power source - - provides the constant voltage output

    belt pressure transmitter the nose - -aerodynamic pressure and the triggering control 

   sealed end clamps - - the fixed two pieces to make up the line sealed end the unit clamp
 2. welding principle

    This equipment belongs to one kind which the resistance pressure welds, mainly constant pressure output which provides through the main engine and the control circuit, in the sealed end contact part, through the looping-in, transforms the electrical energy the heat energy, under the pressure assistance function, the tin copper wire outer layer tin or the tin and the copper mixture and circuit panel copper forms the new alloy, both pass the superfusion nucleus to connect in together.

3. The output way

   Weld head  is a pressure transmitter structure, may establish the triggering pressure in advance, when welding the foot downward steps on, the pressure achieved when setting value electrifies, after the circular telegram, under the sealed end the looping-in, the resistance which in the return route forms gives off heat, when the quantity of heat achieved when the metal the fusing condition needs the temperature, the metal can have the deformation and form the new alloy to connect gradually the line.In here, the movement which the foot stepped on played the very major role, not merely monoenergetic convenience control welding speed and pressure, but also could when welded the fine lace through step on in advance assists to the uneven line.
