Brief description of the drawings
Fig. 1 represents the structural representation of the embodiment of PCB flying probe stationary installation in the utility model.
Embodiment
As shown in Figure 1, shown device comprises the structural representation of the embodiment of PCB flying probe stationary installation:
Fixed head 2 and be opened in the lip-deep pickup groove for fixing PCB1 to be tested of described fixed head one.
By offer the pickup groove of fixing PCB to be tested on fixed head, before carrying out flying probe, described PCB to be tested is fixed in pickup groove, makes the PCB of arbitrary dimension can carry out flying probe, broken through the restriction of existing flying probe platform to PCB size.
The dimensions of described PCB flying probe stationary installation is as follows:
When the thickness of described PCB to be tested is less than 0.5mm, the thickness of described fixed head is 0.5mm.
When the thickness of described PCB to be tested is more than or equal to 0.5mm, the thickness of described fixed head equals the thickness of described PCB to be tested.
When the length of described PCB to be tested is less than or equal to 75mm, the length of described fixed head is 80mm.
The length of side of described PCB to be tested is while being greater than the A of 75mm, and the corresponding length of side of described fixed head is (A+10) mm.
When the thickness a of described PCB to be tested is less than 0.5mm, the degree of depth b of described pickup groove is the thickness a that 0.5mm deducts described PCB to be tested.
When the thickness a of described PCB to be tested is greater than 0.5mm, the thickness a that the degree of depth b of described pickup groove is described PCB to be tested deducts 0.5mm.
When the thickness a of described PCB to be tested equals 0.5mm, the degree of depth b of described pickup groove is 0.05mm.
For example, the thickness of slab of PCB to be tested is 1.0mm, is of a size of: 75mm*75mm, and the thickness of the fixed head of corresponding described PCB flying probe stationary installation is 1.0mm, is of a size of: 80mm*80mm; The degree of depth of described pickup groove is 0.5mm.
