Put, the shape for comparing the corresponding PCBA elements of shape of through hole is adapted；Multiple blind holes, blind hole are additionally provided with cover plate body
Open up the position for being located proximate to polarity dots on PCBA elements, so as to when PCBA elements carry out inspection work on to circuit board,
The cover plate is moved to circuit board direction, and makes each PCBA elements and compares through hole one-to-one corresponding up and down, moves down cover plate sheet afterwards
Body, if after cover plate body reclines with circuit board, comparing and having PCBA elements in through hole, lacked if not for PCBA elements,
Meanwhile carried out compareing the polarity dots on PCBA elements according to the position of blind hole, it is unanimously that PCBA component mounters are correct, conversely,
PCBA component mounter mistakes；If cover plate body can not be moved down and reclined to circuit board, the position that can determine that to move down has more
The PCBA elements of attachment.
In summary, the cover plate of PCBA elements on Comparison Circuit plate is used for using this, can quickly confirm PCBA elements
Whether whether correct, PCBA elements have the problems such as lacking or be unnecessary to polarity, substantially increase the operating efficiency for checking work and inspection
The degree of accuracy is looked into, and greatly reduces the labor intensity of inspection personnel and the injury to eyes, meanwhile, this is used for Comparison Circuit plate
The cover plate of upper PCBA elements is simple in construction, is easy to fabricate, and manufacturing cost is low.
Due to being coated with color in blind hole, so as to be advantageous to the identification of procurator by smearing coloured blind hole, have
Help improve the operating efficiency for checking work.
Because the both ends of cover plate body are equipped with Handheld Division, so as to which in use, inspection personnel holds Handheld Division and moved
Dynamic and operation, substantially increases ease of use.
Because Handheld Division is arc Handheld Division, so as to avoid the presence at tip by arc Handheld Division, effectively prevent
The accident for contacting with inspection personnel and being damaged to inspection personnel on the move occurs.
Because the length of cover plate body is more than the length of circuit board, the width of cover plate body is more than the width of circuit board, from
And enable cover plate body that circuit board is completely covered, to check that all PCBA elements on circuit board are laid a good foundation；Due to
The thickness of cover plate body is less than the thickness of most thin PCBA elements on circuit board, so that in cover plate body in use, passing through the knot
Structure causes all PCBA elements can pass through to compare through hole and expose, so that inspection personnel can fast and accurately judge
The presence or absence of PCBA elements.
Because the thickness of cover plate body is 1mm, after the covering on circuit boards of cover plate body, the periphery of cover plate body is protruded
1mm, so as on the basis of need of work is met, realize small volume, effect in light weight.
Due to being pasted with label on cover plate body, so as to can be labeled by label thereon, so as to plurality of specifications,
Rapid identification is carried out in the circuit board of model.
