When, at this moment need it is charged signal and component state exported to printed board are detected, determine trouble point and component work shape
Whether state is normal.It is limited due to reinforcing chassis space, can not directly signal be surveyed to required test and surveyed with test instrumentation, instrument
Examination, the method for generally use are：First cabinet is powered off, takes out printed board to be tested, and by required test in printed board
Signal carries out fly line extraction, then printed board is mounted in cabinet.It re-powers and the line end of extraction is tested.This test
Method is time-consuming and laborious, it is also possible to which, since misoperation triggers secondary failure, there are potential risks for this method.
The content of the invention
In order to overcome the shortcomings of existing test method poor practicability, the present invention provides a kind of printed board switching test method.
This method takes out printed board to be measured under controlling machine box off-position out of controlling machine box；Adapter plate for circuit is welded into plug
End inserts in printed board slot position to be measured in controlling machine box；Printed board to be measured is vertically inserted in controlling machine box external circuit pinboard to insert
Seat end；It is powered on to controlling machine box, needs to survey required test point in printed board by test instrumentation, instrument according to test
Examination.The present invention transfers printed board to be measured outside controlling machine box, and tester can use the tests such as universal meter, oscillograph to set
Whether all of the port of standby live line measurement device, working condition and each signal input/output state for observing component are normal.
Ensure live testing pwb signal using circuit board switching test method, quick and precisely judge printed board trouble point, improve
Work efficiency avoids fly line and draws the secondary failure triggered when signal measures due to misoperation, and practicability is good.
The technical solution adopted by the present invention to solve the technical problems：A kind of printed board switching test method, its main feature is that
Comprise the following steps：
Step 1: design adapter plate for circuit, adapter plate for circuit stretches out controlling machine box, and adapter plate for circuit both ends are installed with to be measured
The plug J1 of printed board same model and with plug J1 models matched socket J2, the wherein edge of plug J1 and pinboard
Coincident, each core of plug J1 and socket J2 of adapter plate for circuit pass through printed board component side or welding surface wiring connection.
Step 2: under controlling machine box off-position, printed board to be measured is taken out out of controlling machine box；
Step 3: adapter plate for circuit plug J1 ends are inserted into the corresponding socket of printed board to be measured on cabinet inner bottom plating,
Ensure that plug J1 female contacts corresponding with printed board to be measured are good, fasten.
Step 4: the socket end of adapter plate for circuit is located at outside cabinet, printed board to be measured is vertically inserted in adapter plate for circuit
Socket J2 on, edge connector to be measured contacts good, fastening with pinboard socket J2.
Step 5: being powered on to controlling machine box, printed board to be measured is located at outside controlling machine box, uses universal meter, oscillograph band
Whether all of the port of electrical measurement metering device, working condition and each signal input and output for observing device are normal.
The beneficial effects of the invention are as follows：This method is under controlling machine box off-position, by printed board to be measured from controlling machine box
Interior taking-up；Adapter plate for circuit welding plug end is inserted in into printed board slot position to be measured in controlling machine box；Printed board to be measured is hung down
Straight cutting is in controlling machine box external circuit pinboard socket end；It powers on to controlling machine box, is needed according to test through test instrumentation, instrument
Required test point in printed board is tested.The present invention transfers printed board to be measured outside controlling machine box, and tester can
To use all of the port of the test equipments live line measurement device such as universal meter, oscillograph, the working condition of component and each is observed
Whether a signal input/output state is normal.Using circuit board switching test method guarantee live testing pwb signal, quickly
Accurate judgement printed board trouble point, improves work efficiency, and avoids fly line and draws when signal measures due to misoperation
The secondary failure of initiation, practicability are good.
It elaborates with reference to the accompanying drawings and detailed description to the present invention.
