摘要:
Disclosed is a printed circuit board comprising a contact terminal, which prevents a poor contact and reduces a manufacturing cost, and an image forming apparatus having the same. The printed circuit board comprises a circuit part for controlling and processing an operation of electronic appliance, and a large-area contact terminal formed by a group of small-area terminals for electric connection with external device. The small-area terminals can be formed in various types, respectively having regular size and shape and being distanced a predetermined interval. Accordingly, unevenness of the large-area contact terminal surface caused by soldering is prevented since a plurality of small-area terminals constitute a unit contact terminal of over a predetermined size. Therefore, quality of contact with external terminal improves. Further, manufacturing cost is reduced, and the manufacturing process becomes simple.
