Description
Technical field
The utility model relates to a kind of tool, especially a kind of vacuum two-part tool.
Background technology
Electronic circuit circuit board (pcb board) needs to experience a lot of links in process of production, and each link all needs the quality that corresponding testing tool comes testing product.Tool is a platform that the pcb board test is provided, and its principle of work is to utilize probe with tested point on the pcb board and the corresponding point conducting in the test machine, realizes final test by calling program corresponding in the test machine.
Existing jig structure as shown in Figure 1 and Figure 2.Tool is divided into upper and lower mould, protection up and down support plate, needle plate, up and down plate and support column up and down, all kinds of positioning systems, height probe and output P-PIN or interface board adjunction lancet.Wherein the bottom of the counterdie shown in the figure is fixed on the test machine; support plate is used for protecting probe and board under test and locatees board under test with the guide pillar on the support plate and makes the probe alignment test point up and down; positioning system is to guarantee that test point and probe can accurately locate, and P-PIN or interface board adjunction lancet are to be used for transferring corresponding point in probe and the tester table.Probe assembly is divided into probe and needle guard, and probe is fixed on the needle plate by the needle guard ring, and back-moving spring guarantees to test the back probe at every turn and support plate can both reset.
But, in use also there are some problems in the tool of existing structure: the Power on test that is used in ATE (or ICT): at all ATE (or ICT) test machine the function of last electrical testing is arranged all, can make the power on function measurement of laggard line number word assembly of UUT (board under test) part behind the Poweron (powering on).Circuit board function more and more stronger (line construction is also complicated more) in recent years, also exquisite more electricity-saving function (operating voltage is also low more); When the Power on stage is tested in the pressing of ATE tool, some digital assembly can cause impedance to increase by Yin Teding Nets (line node) contact probe, causes defencive function and causes this class component can't carry out functional test because of obtaining specified operating voltage.
Traditional settling mode at these problems:
1. with manually these pin marks being pulled out one by one, test again, the disadvantage factor of doing like this is: if these pin marks are pulled out one by one, can cause covering the rate deficiency the containing of test part of product test, produce some part and can't test the product yield is impacted indirectly.When the plug probe, make the needle guard skew easily in addition, cause accurately engaged test point of probe, influence test result.
2. the vacuum tool of tradition use height probe uses so only limit to the single face tool because of spring and probe power skewness.
