What problems should be paid attention to when choosing a plate for a test fixture?



The selection of test fixture plates and the accuracy of drilling play a key role in the accuracy of the entire test fixture. The plates used in the test fixture are generally acrylic (plexiglass), epoxy resin plates, etc.

The common test fixture is a fixture with a probe hole diameter larger than 1.00 mm. The test fixture plate is mostly plexiglass, which is cheap. At the same time, plexiglass is relatively soft. When drilling, the expansion and contraction of the probe sleeve and the hole are closely combined. , Since the plexiglass is transparent, the test fixture is very easy to check for problems. However, ordinary plexiglass is easy to melt and break the drill bit when drilling, especially when the hole diameter is less than 0.8 mm, the problem is very big. Generally, when the hole diameter is less than 1 mm, epoxy resin sheets are used, and epoxy resin sheets are used for drilling. It is not easy to break the drill bit, its toughness and rigidity are good, but the price is more expensive, and the epoxy resin board does not expand or shrink, so if the drilling hole diameter is not accurate, it will cause the probe casing and the hole to be loose and shake. The epoxy resin board is opaque. If there is a problem with the test fixture, it is more difficult to check. In addition, the temperature difference deformation of the plexiglass is larger than that of the epoxy resin board. If the test density is very high, the epoxy resin board should be used.

The test fixture plate has an improved plexiglass, which has the advantages of small deformation, high temperature resistance and a thickness of 5 mm. The 0.6 mm drill bit can drill through the drill bit continuously at one time. The price is slightly higher than ordinary plexiglass but lower than that of epoxy resin sheet. A very good choice.
