Embodiment

[0032] Embodiment: The following takes the clock transfer module as an example to introduce a preferred embodiment of the present invention. The tested module 01 is a clock transmission module, which uses double rows of 20-core "stamp holes" as the module signal lead-out and input pins. The diameter of the "stamp holes" is 0.66mm, and the center point distance between two adjacent "stamp holes" is 1.27mm, the spacing between two rows of pins is 25mm, and the thickness of the printed board is 1mm.

[0033] According to the appearance characteristics of the tested module 01, the entire test fixture is designed to use a spring-retractable test needle with a needle head, which is crimped from both sides to the middle, so as to achieve the purpose of clamping the module and leading out and inputting signals. Through the cooperation of various parts, the problems such as the arrangement and fixing of the test pins at 1.27mm pitch, and how to freely clamp and loosen the test pins to ...

Abstract

The invention discloses a "stamp hole" packaging module test fixture, one end of the base is provided with a boss, the middle of the boss is provided with a screw hole, and the screw hole is equipped with a screw rod; the other end of the base is installed with a protective cover, the protective cover The other side of the first printed board is covered on the concave part, the convex body of the concave part is fixed with a pressure plate by screws, and the pressure plate covers the U-shaped table top of the convex part. The invention uses printed circuit boards to fix the test needles, which ensures the accuracy of the distance between the test needles; the method of screw and spring is used to control the free clamping and loosening of the printed circuit board from both sides to the middle, and the test fixture can be used while fixing the module. Lead out or input the module signal. The invention has the advantages of small volume, low cost, easy processing and manufacture, long service life, high reliability, convenient operation and no damage to the tested module. Moreover, the utility model has good applicability and expansibility, and has a wide range of application fields.

Description

technical field [0001] The invention relates to electrical module testing technology, in particular to a "stamp hole" packaging module testing fixture. [0002] technical background [0003] "Stamp holes", also known as half-hole pads, are originally a jigsaw method used when making printed boards. Later, because of their convenient processing, low cost, and reliable welding, they are often used by some circuit modules with relatively independent functions. As a signal output, it has become a new packaging form, that is, "stamp hole" packaging, such as WiFi modules, USB modules, etc. The "stamp hole" packaging form is suitable for patch welding, and the signal output pin has no connector to connect the module and the bottom plate, so as to achieve the purpose of reducing cost and volume. Since the signal output pin has no connector, but is directly output from the pad holes on both sides of the module, it brings trouble to the module test. The current test method uses the m...
