Abstract
The utility model provides a measuring tool capable of detecting the PCB element pin scolding tin height. The measuring tool includes a height dial gauge and an installing seat which can fix the height dial gauge. The installing seat is fixedly connected with an adjusting seat via a screw. The adjusting seat is provided with adjusting nuts and slide grooves of slide supporting blocks, and the adjusting nuts and the slide grooves are fixedly arranged in symmetry. The adjusting screw arranged on the adjusting nut is connected with the slide supporting block. The centre of a gauge rod of the height dial gauge fixed on the installing seat is provided with a measuring rod, and an end head of a measuring end of the measuring rod is provided with a pin inserting hole. After the height dial gauge on the installing seat is connected with the measuring rod to set the measuring reference, the pin inserting hole of the measuring rod of the measuring tool can be inserted into an element pin of a PCB to measure the height of the scolding tin. As long as the measuring rod is pressed back by a distance by the pin scolding tin, the height dial gauge acquires a precise measuring value of the pin scolding tin, thus making the height of the scolding tin of an electrical element pin accord with the design requirements.
Description
Technical field
The utility model belongs to printed-wiring board (PWB) manufacturing technology field, relates to a kind of pcb board testing tool, is specifically related to a kind of pcb board component pin scolding tin height detection measurer.
Background technology
The pcb board of electronic product is through behind the DIP wicking packaging electronic parts; In order to prevent that the electronic devices and components pin is few because of last tin amount; The long-time direct problems that influences performance of products and life-span such as causing tin is aging, weathering of using adopts artificial visually examine's mode to detect pin scolding tin height usually.This mode not only efficient is low but also accuracy rate is not high; Especially the last tin height through the bigger electronic devices and components pin of electric current has strict demand; Do not have special-purpose measurement its according to detection, tend to cause pcb board big quality problem to occur with the mode of existing manual range estimation, consequence is more serious.
The utility model content
The purpose of the utility model provides a kind of pcb board component pin scolding tin height detection measurer; With on its insertion component pin last tin height accurately being measured; At any time monitor DIP encapsulation wicking effect; Guarantee to adhere to specification, solved the problems referred to above that exist in the existing pcb board DIP wicking encapsulation through the last tin height of the bigger electronic devices and components pin of electric current.
The technical scheme that the utility model adopted is; A kind of pcb board component pin scolding tin height detection measurer; The mount pad that comprises a height dial gauge and level altitude dial gauge, described mount pad are screwed with the adjustment seat and are connected, and described adjustment seat offers the chute of symmetrical hard-wired adjustment nut and sliding support piece respectively; The adjustment screw that is equipped with on the described adjustment nut connects the sliding support piece, in the height dial gauge table bar center that said mount pad is fixing sounding rod is housed.
The described pcb board component pin of the utility model scolding tin height detection measurer, its characteristic also be,
The termination of described sounding rod measuring junction is provided with the pin patchhole.
The internal diameter of described pin patchhole is the correspondingly-sized of different elements leg diameter.
The utility model pcb board component pin scolding tin height detection measurer; Setting height(from bottom) dial gauge and connect sounding rod in mount pad; Configure measuring basis; Just can the pin patchhole of the sounding rod of test measuring device be inserted on the component pin pin scolding tin height is measured, sounding rod is pushed up back a distance by pin scolding tin, has just obtained the accurate measured value of a pin scolding tin height on the height dial gauge.The utility model is easy to use, can monitor DIP encapsulation wicking effect at any time, adheres to specification with the scolding tin height that satisfies on the electronic devices and components pin, guarantees the quality of product.
Description of drawings
Fig. 1 is the utility model pcb board component pin scolding tin height detection measurer structural representation;
Fig. 2 is that the utility model is measured pcb board component pin scolding tin height user mode synoptic diagram.
Among the figure, 1. height dial gauge, 2. mount pad, 3. adjustment seat, 4. adjustment nut, 5. sliding support piece, 6. chute, 7. adjustment screw, 8. sounding rod, 9. pin patchhole, 10.PCB plate, 11. component pins, 12. pin scolding tin.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.A kind of pcb board component pin scolding tin height detection measurer; As shown in Figure 1; The mount pad 2 that comprises a height dial gauge 1 and level altitude dial gauge, described mount pad 2 are screwed with adjustment seat 3 and are connected, and described adjustment seat 3 offers the chute 6 of symmetrical hard-wired adjustment nut 4 and sliding support piece 5 respectively; The adjustment screw 7 that is equipped with on the described adjustment nut 4 connects sliding support piece 5; In said mount pad 2 fixing height dial gauge 1 table bar centers sounding rod 8 is housed, the termination of described sounding rod 8 measuring junctions is provided with pin patchhole 9, and the internal diameter of pin patchhole 9 is the correspondingly-sized of different elements leg diameter.
When the utility model pcb board component pin scolding tin height detection measurer uses; As shown in Figure 2; According to the component pin 11 scolding tin height and the leg diameter size of different pcb board 10, select and pin patchhole 9 corresponding inner diameter measurement bars 8, sounding rod 8 is connected to height dial gauge 1 table bar center; Let the termination and concordant being screwed in sliding support piece 5 terminations of sounding rod 8; Rotate height dial gauge 1 dial plate again and make zero, then the utility model pcb board component pin scolding tin height detection measurer is inserted on the component pin 11 of pcb board 10, the height of pin scolding tin 12 is measured by pointer.The component pin 11 of pcb board 10 is inserted by the pin patchhole 9 of sounding rod 8 terminations; The pin scolding tin 12 that exceeds upwards pushes up back a distance with sounding rod 8 terminations; And, on the height dial gauge, just obtained the accurate measured value of pin scolding tin height by sounding rod 8 drive height dial gauges 1 table bar retraction.
Has the horizontal positioned that other element influences back-up block 5 owing to measure the some position of pin scolding tin 12; Can rotate test measuring device or rotate two adjustment screws 7 on the adjustment seat 3; Drive sliding support piece 5 through adjustment screw 7 and in chute 6, move certain distance; Satisfy sliding support piece 5 and avoid other element on the pcb board 10, let two sliding support pieces 5 on pcb board 10, accurately locate, obtain the accurate measured value of pin scolding tin 12 scolding tin height.
The utility model is easy to use, can monitor DIP encapsulation wicking effect at any time, adheres to specification with the scolding tin height that satisfies on the electronic devices and components pin.
Above-mentioned embodiment is an instance of the utility model; Not enforcement and the interest field that is used for limiting the utility model; All equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
