What kind of wafer probe is good

Introduction: Tungsten-tungsten probes basically use tungsten-niobium alloy wire containing 3% niobium, with a diameter of 0.05-0.1mm. The tungsten-germanium alloy wire containing 3% of niobium was cut into a length and straightened.

At present, the germanium-tungsten probes used in China are all imported from Japan. The germanium-tungsten probes from Japan have good quality and excellent performance, but the price is so high that many domestic companies can hardly bear a heavy burden. However, domestic production of such a tungsten-niobium alloy wire containing 3% of niobium has a quality close to that of Japan. The price is very good. PCB probes are used to detect components after mounting components. The core technology of high-end products is still in the hands of foreign companies. Some probe products have been successfully developed and can replace imported probe products.

The main production process is semiconductor integrated circuits, generally large-scale integrated circuits. Shenzhen Degang Electronic Equipment Design Department can provide test probe stations, 12-inch wafer manual probe stations, and probe cards (data available, physical production) , probe card production equipment and technology, wafer probes, TF card packaging machine (a molding, the entire board into, single-chip out, do not need cutting equipment).
