Abstract
The utility model discloses a PC board carbon ink resistance testing device, which comprises a PC board tester and a carbon ink testing gauge. The carbon ink testing gauge is provided with multiple pairs of probes. Each pair of probes comprise two probes. The positions of each pair of probes correspond to the two ends of a carbon ink bar on a PC board. After the PC board is fixed on the carbon ink testing gauge, each pair of probes contact with the two ends of the corresponding carbon ink bar. The PC board tester is provided with a program for testing carbon ink resistance. The probes are connected with the PC board tester through wires. The PC board carbon ink resistance testing device can automatically test the resistance of each carbon ink bar with high efficiency and discriminate the PC board with substandard resistance. The test time only needs about three seconds. Measure time is reduced greatly and the test is automatic, thus labor force is saved, artificial influence is avoided and the test precision is higher.
Description
Technical field
The utility model relates to a kind of device that is used for carbon ink resistance on the testing printed circuit board, relates to specifically that a kind of test speed is fast, accurate testing and save the carbon ink resistance proving installation of manpower.
Background technology
After the last carbon ink of printed circuit board (PCB) (PCB) finishes printing, need to the carbon ink bar carry out resistance test judge whether qualified, common way is, operating personnel adopt multimeter that the carbon ink bar on the printed circuit board (PCB) is tested by root, generally have tens carbon ink bars on the printed circuit board (PCB), if the plank with more than 40 carbon ink bar is tested, more skilled operating personnel need test every four to five minutes time of plank cost, note the resistance data of measurement then, and select maximal value and minimum value, resistance difference is chosen greater than 400 ohm plank, promptly scrapped as unacceptable product.Not only test speed is slow, labor intensive for the mode of this artificial employing multimeter test carbon ink resistance, and test accuracy is subject to the human factor influence.
Defective at artificial employing multimeter test carbon ink resistance, occur some on the market and be specifically designed to the carbon ink resistance test machine of test carbon ink resistance, though can improve the speed and the precision of test, and liberated manpower, but increased equipment input and equipment cost height, and then improved the printed circuit board (PCB) production cost of products.
All to use the printed circuit board test machine in the printed circuit board (PCB) production run, the major function of printed circuit board test machine does not still possess carbon ink resistance test function for detecting and filter out printed circuit board (PCB) defective on the electrical properties such as open circuit, short circuit or electric leakage that cause in process of production.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of printed circuit board (PCB) carbon ink resistance proving installation, and the test speed of this printed circuit board (PCB) carbon ink resistance proving installation is fast, degree of accuracy is high, and has saved manpower.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of printed circuit board (PCB) carbon ink resistance proving installation, comprise printed circuit board test machine and carbon ink measurement jig, described carbon ink measurement jig is provided with some to probe, each is made of two probes probe, the position of every pair of probe is corresponding with carbon ink bar two ends on the printed circuit board (PCB), after printed circuit board (PCB) is fixed on the described carbon ink measurement jig, every pair of probe contacts with its corresponding carbon ink bar two ends respectively, on the described printed circuit board test machine program that is used to test the carbon ink resistance is installed, is connected with lead between described probe and described printed circuit board test machine.The utility model increases the program that is used to test the carbon ink resistance in original printed circuit board test machine, and designed the carbon ink measurement jig, because the carbon ink measurement jig has many to probe, all carbon ink bar two ends on the printed circuit board (PCB) can contact with corresponding probe simultaneously, increased the printed circuit board test machine of the program that is used to test the carbon ink resistance on cooperating again, resistance that can automatic and high efficiency each carbon ink bar of test, and the printed circuit board (PCB) of resistance difference greater than 400 ohm distinguished, this printed circuit board (PCB) carbon ink resistance proving installation general test time only needs about three seconds, manually use the multimeter test to need four or five minutes compared with tradition, significantly reduced Measuring Time, and test automation, not only save manpower, also avoided artificial factor, made measuring accuracy higher.
Described lead is the ox horn winding displacement.
The beneficial effects of the utility model are: printed circuit board (PCB) carbon ink resistance proving installation of the present utility model is to increase the program that is used to test the carbon ink resistance in original printed circuit board test machine, and designed the carbon ink measurement jig, because the carbon ink measurement jig has many to probe, all carbon ink bar two ends on the printed circuit board (PCB) can contact with corresponding probe simultaneously, increased the printed circuit board test machine of the program that is used to test the carbon ink resistance on cooperating again, resistance that can automatic and high efficiency each carbon ink bar of test, and the printed circuit board (PCB) of resistance difference greater than 400 ohm distinguished, this printed circuit board (PCB) carbon ink resistance proving installation general test time only needs about three seconds, manually use the multimeter test to need four or five minutes compared with tradition, significantly reduced Measuring Time, and test automation, not only saved manpower, also avoid artificial factor, made measuring accuracy higher.
