??personalized printed circuit board manufacturers to teach you how to use cardboard fast circuit board production
??Custom printed circuit board manufacturing?Not only can the circuit board cardboard. Fast and convenient, the effect is very good. Specific operation method according to the following:
??A, components layout
??Take a piece of about 1-1.5mm thick cardboard, the welding components in a board placed a large arrangement, as far as possible to make the welding near each element with a pin joint.
??The OTL circuit as shown above, the elements are arranged plate as shown below, element position basically is according to the circuit diagram of the arrangement, visible layout is very convenient, it is the first advantage. circuit board manufacturing companies.
??Two, drilling
??Element must eventually put on the board, and one of the ordinary circuit board are similar, but in contrast, the board holes can be much more easily, it is making circuit board board second advantages. Perforation, can first use the component pin on the cardboard cardboard pressed gently, leaving small pits corresponding, use this small pit, stabbed with a needle to wear, can easily be element is positioned in a board. With black spots in the place that is the drilling position.
??Three, welding
??In order to wear element, because the component pin layout is very close to the * the welding may be the same node of each pin directly lap welding, some larger components, such as capacitors and the feedback element, may be appropriate to lead, can use the wire of 0.5mm diameter enameled wire leads .Lj increasing circuit clean, welding should keep the distance between solder joints, to prevent a short circuit.
??After the above steps, then made a circuit board, circuit board production using this method is not only easy to operate, and can be done very compact circuit. Practice has proved, in the dry environment, as long as the voltage is not too high ( high voltage with the cardboard production is a little too hasty ), the pressure is not all can achieve satisfactory results, but if the use of distributed capacitance in high frequency circuit may be great, but the design consideration, board also can.
