[0020] The utility model will be further described below in combination with the drawings. The following embodiments are only used for more clearly illustrating the technical scheme of the utility model, and cannot be used to limit the protection scope of the utility model.
[0021] As shown in Figure 1 and Figure 2 The utility model embodiment provides a packaging and sampling inspection protection jig, including main body 1, main body 1 adopts aluminum alloy material, and the weight is controlled at 250 ~ 270g, and it is convenient for staff to take and is light, and the total thickness is controlled at 12 ~ 14mm, and it is convenient for staff to use under the market general microscope, avoids being too thick, and ordinary microscope cannot be focused, thereby cannot be inspected whether the appearance of product is abnormal, and in the embodiment, the length of main body 1 is 26cm, and the width is 8cm.
[0022] The surface of main body 1 is treated by anodic blackening, which helps to reduce cost, increase product scratch and wear resistance, and can be used for 10 years under normal use.
[0023] There are recesses on the front and back sides of the main body 1, one side of the recess extends to the outside of the main body, and grooves are provided on the other three circumferential sides. Only one side is extended to the outside of the main body to facilitate the product material strips to slide from the other side and be damaged during the random inspection process.
[0024] Furthermore, in some embodiments, an opening 6 is provided in the middle of one side of the recess extending to the outside of the main body, and the opening 6 is used for inserting fingers to take the material strip to prevent the material strip from being damaged when taking it.
[0025] In this embodiment, the grooves include a first groove 2, a second groove 3 and a third groove 4. The length of the first groove 2 is 24.5 cm and the width is 7.1 cm, which is suitable for DFN&BGA&QFN product strips. The length of the second groove 3 is 21.5 cm and the width is 7.0 cm, which is suitable for DIP product strips. The length of the third groove 4 is 25.5 cm and the width is 7.3 cm, which is suitable for SOP product strips.
[0026] In some embodiments, recessed holes are provided on both sides of the first groove 2 and the third groove 4 on the side corresponding to the side where the recess extends to the outside of the main body 1. There are a total of 4 recessed holes. Tweezers can be easily inserted through the recessed holes to push the material strip, avoiding direct contact between the tweezers and the surface of the product material strip, which would cause product scrapping and pollution.
[0027] In some embodiments, the ends of the grooves are all curved, using curved angles instead of right angles, which helps the product strips slide along the grooves into the jig, avoiding jamming or bending of the product strips.
[0028] The working principle of this utility model includes:
[0029] Select the appropriate groove according to the type of product strip to be tested, then place the fixture on the microscope workbench, push the product strip to be tested into the appropriate groove through the opening side, and slide it into the fixture until it can no longer be pushed. At this point, you can start the packaging inspection. During the packaging inspection, hold both ends of the fixture with both hands and move it under the microscope for inspection.
[0030] When picking up a strip of material for confirmation during spot checks, insert your fingers into the opening to pick up the strip, avoiding picking up from above and touching the product, which could cause contamination or scrapping.
[0031] After the random inspection is completed, insert the tweezers into the concave hole to push the material strip to the opposite side until the material strip moves into the material box carrier.
[0032] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should also be considered as the protection scope of the present application.
