The invention discloses an on-line test fixture with pneumatic probes. The test fixture comprises an upper test assembly and a lower test assembly which are arranged symmetrically in an upper and down manner. Each of the upper test assembly and the lower test assembly includes a carrying plate, a probe plate, a side plate, a plurality of reset springs, a plurality of supporting columns and a plurality of ordinary probes. The mainboard of the notebook computer is arranged between the carrying plate of the upper test assembly and the carrying plate of the lower test assembly, and on-line test is performed on the mainboard of the notebook computer through the plurality of ordinary probes. Each of the upper test assembly and the lower test assembly further includes a plurality of pneumatic probes, wherein the plurality of pneumatic probes are fixed on the probe plate and pass through the corresponding carrying plate, and on-line test is performed on the mainboard of the notebook computer through the plurality of pneumatic probes and the ordinary probes. According to the on-line test fixture with pneumatic probes, not only booting test can be performed on an ICT fixture, and but also the test range of the ICT fixture can be extended, so the functional testing of complex chips, such as CPU/PCH/EC/DDR, can be added.
Description
Technical field
The present invention relates to a kind of equipment that main board for notebook computer is carried out to on-line testing, particularly a kind of on-line testing tool with pneumatic probe.
Background technology
Company is current in the time producing main board for notebook computer, and electronic circuit surface-assembled (SMT) stage need be carried out on-line testing (ICT) to mainboard, is uploaded to SMT processing procedure production system (Shop floor) after being completed.Method and the step of ICT test are as follows: the first step, on main board for notebook computer (M/B), plug CPU/RAM; Second step, brush mainboard sequence number (M/B Serial Number); The 3rd step, mainboard is put into tool, and machine presses down test (as shown in Figure 1); The 4th step, test is by delivering to result Shop floor system.Conventionally the interference to main board for notebook computer due to board and tool itself, cannot carry out more comprehensively functional test to mainboard, again because conventional ICT tool is in completing simulation electronic component (Analog) test, again mainboard is carried out to upper electrical measurement mainboard voltage and numeral (digit) test, therefore, conventional ICT method of testing can only be tested the unfavorable conditions such as the open circuit, short circuit, voltage of part, cannot test functional bad.
Summary of the invention
The object of this invention is to provide a kind of on-line testing tool with pneumatic probe, not only can realize start test at ICT tool, the scope that has also expanded the test of ICT tool, has increased the functional test of the complex chip such as the integrated south bridge of CPU/ (PCH)/embedded controller (EC)/Double Data Rate synchronous DRAM (DDR).
In order to realize above object, the present invention is achieved by the following technical solutions:
A kind of on-line testing tool with pneumatic probe, comprise upper and lower symmetrically arranged upper test suite and lower test suite, described upper test suite and lower test suite comprise respectively: support plate, needle plate, side plate, some back-moving springs, some support columns and some common probes; Placing laptop mainboard between described upper test suite and the support plate of lower test suite, by some common probes, main board for notebook computer is carried out to on-line testing, upper test suite and lower test suite also comprise respectively: some pneumatic probes, some described pneumatic probes are fixed on needle plate and through corresponding support plate, by some pneumatic probes and common probe, main board for notebook computer are carried out to on-line testing.
The syringe needle of described pneumatic probe can be in the housing of pneumatic probe free-extension, when the distance of corresponding needle plate and main board for notebook computer increases, after corresponding common probe separates with main board for notebook computer, by pneumatic mode, the syringe needle of pneumatic probe is extruded, make the contact of its contact main board for notebook computer.
The present invention compared with prior art, has the following advantages:
Not only can realize start test at ICT tool, also expand the scope of ICT tool test, increase the functional test of the complex chip such as CPU/ PCH/EC/DDR.

Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 2, a kind of on-line testing tool with pneumatic probe, comprise upper and lower symmetrically arranged upper test suite and lower test suite, described upper test suite and lower test suite comprise respectively: support plate 1, needle plate 2, side plate 4, back-moving spring 3, support column 5 and some common probes 6; Placing laptop mainboard 8 between described upper test suite and the support plate 1 of lower test suite, by some common probes 6, main board for notebook computer 8 is carried out to on-line testing, upper test suite and lower test suite also comprise respectively: some pneumatic probes 7, some described pneumatic probes 7 are fixed on needle plate 2, pneumatic probe 7 on the needle plate 2 of upper test suite and lower test suite through each self-corresponding support plate 1, carries out on-line testing by some pneumatic probes 7 and common probe 6 to main board for notebook computer 8 respectively.
(tool top and the bottom test philosophy is identical) as shown in Figure 4, the syringe needle of pneumatic probe 7 can be in the housing of pneumatic probe 7 free-extension, when corresponding needle plate 2 and the distance of main board for notebook computer 8 increase, after the common probe 6 of its correspondence separates with main board for notebook computer 8, by pneumatic mode, the syringe needle of pneumatic probe 7 is extruded, make the contact 81 of its contact main board for notebook computer.
In the time using, as shown in Figure 3, main board for notebook computer 8 is carried out to Analog and Digit test, now, the contact 81 that common probe 6 contacts main board for notebook computer completes test, and pneumatic probe 7 does not contact contact 81, after the test that completes the aforesaid first stage, while starting shooting test, as shown in Figure 4, test suite and lower test suite are gone up in tool top and the bottom, controlled being separated by a distance, common probe 6 departs from, do not contact main board for notebook computer 8, controlling pneumatic probe 7 contacts and relates to start measuring point on main board for notebook computer 8, and start power supply and starting-up signal are provided to the main board for notebook computer 8 that is inserted with RAM and CPU by pneumatic probe 7, complete start test, also increased the functional test of the complex chip such as the integrated south bridge of CPU/ (PCH)/embedded controller (EC)/Double Data Rate synchronous DRAM (DDR) simultaneously.
In sum, a kind of on-line testing tool with pneumatic probe of the present invention, not only can realize start test at ICT tool, the scope that has also expanded the test of ICT tool, has increased the functional test of the complex chip such as the integrated south bridge of CPU/ (PCH)/embedded controller (EC)/Double Data Rate synchronous DRAM (DDR).
