Description

A kind of measurement jig that notebook computer is carried out on-line testing

Technical field

The utility model relates to a kind of equipment that main board for notebook computer is carried out on-line testing, particularly a kind of measurement jig that notebook computer is carried out on-line testing.

Background technology

Company is current when producing main board for notebook computer, and electronic circuit surface-assembled (SMT) stage needs mainboard is carried out on-line testing (ICT), 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, plug CPU/RAM on main board for notebook computer (M/B); Second step, brush mainboard sequence number (M/B Serial Number); In the 3rd step, mainboard is put into tool, and machine presses down test (as shown in Figure 1); In the 4th step, test is by delivering to result Shop floor system.Usually due to the interference to main board for notebook computer of board and tool itself, can't carry out more comprehensively functional test to mainboard, again because conventional ICT tool is completed in simulation electronic component (Analog) test, again mainboard is carried out 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, can't test functional bad.

The utility model content

The purpose of this utility model is to provide a kind of measurement jig that notebook computer is carried out on-line testing, not only can realize the start test at the ICT tool, also enlarge the scope of ICT tool test, increased the functional test of the integrated south bridge of CPU/ (PCH)/embedded controller (EC)/complex chip such as Double Data Rate synchronous DRAM (DDR).

In order to realize above purpose, the utility model is achieved through the following technical solutions:

A kind of measurement jig that notebook computer is carried out on-line testing, comprise the symmetrically arranged upper test suite in up and down 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 the support plate of described upper test suite and lower test suite, by some common probes, main board for notebook computer is carried out on-line testing, upper test suite and lower test suite also comprise respectively: some pneumatic probes, described some pneumatic probes are fixed on needle plate and pass corresponding support plate, by some pneumatic probes and common probe, main board for notebook computer are carried out on-line testing.

The syringe needle of described pneumatic probe can be in the housing of pneumatic probe free-extension, when the distance of the needle plate of correspondence and main board for notebook computer increases, corresponding common probe is with after main board for notebook computer separates, extrude by the syringe needle of pneumatic mode with pneumatic probe, make the contact of its contact main board for notebook computer.

The utility model compared with prior art has the following advantages:

Not only can realize the start test at the ICT tool, also enlarge 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 better specific embodiment in detail, the utility model is further elaborated.

As shown in Figure 2, a kind of measurement jig that notebook computer is carried out on-line testing, comprise the symmetrically arranged upper test suite in up and down 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 the support plate 1 of described upper test suite and lower test suite, carry out on-line testing by 6 pairs of main board for notebook computer of some common probes 8, upper test suite and lower test suite also comprise respectively: some pneumatic probes 7, described some 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 passes respectively each self-corresponding support plate 1, carries out on-line testing by some pneumatic probes 7 and 6 pairs of main board for notebook computer of common probe 8.

(tool top and the bottom test philosophy 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 the needle plate 2 of the correspondence distance with main board for notebook computer 8 increases, the common probe 6 of its correspondence is with after main board for notebook computer 8 separates, extrude by the syringe needle of pneumatic mode with pneumatic probe 7, make the contact 81 of its contact main board for notebook computer.

when using, as shown in Figure 3, main board for notebook computer 8 is carried out Analog and Digit test, at this moment, test is completed in the contact 81 of common probe 6 contact main board for notebook computer, and pneumatic probe 7 does not contact contact 81, after the test of completing the aforesaid phase one, when starting shooting test, as shown in Figure 4, test suite and lower test suite are namely gone up in the tool top and the bottom, controlled being separated by a distance, common probe 6 breaks away from, do not contact main board for notebook computer 8, control and relate to the start measuring point on pneumatic probe 7 contact main board for notebook computer 8, and start power supply and starting-up signal are provided for the main board for notebook computer 8 that is inserted with RAM and CPU by pneumatic probe 7, complete the start test, also increased simultaneously the functional test of the integrated south bridge of CPU/ (PCH)/embedded controller (EC)/complex chip such as Double Data Rate synchronous DRAM (DDR).
