【Embodiment】
Paste solder printing fixing device of the present utility model, suitable for by paste solder printing in PCBA board（It is not shown）On electronics
Element（It is not shown）Surrounding, in the present embodiment, two positioning holes are provided with the left of the electronic component（It is not shown）, right side is provided with certain
Position hole（It is not shown）, the corner location of the electronic component is provided with four connecting holes（It is not shown）, the paste solder printing fixing device bag
Include steel mesh 1, press box 2, the fastener 4 of bottom plate 3 and two.
Refer to shown in Fig. 1-4, the steel mesh 1 is arranged on the electronic component in the PCBA board, and its center is provided with a fluting
11, for being arranged the electronic component, the fluting 11 be surrounded by it is some opening 12, tin cream from this it is some opening 12 at print to
PCBA board, the both sides of steel mesh 1 respectively to should three positioning holes be provided with three net positioning holes 13, the corner location pair of the fluting 11
Should four connecting holes be provided with four net connecting holes 14.
The press box 2 is arranged on the steel mesh 1, and the lower end of press box 2 corresponds to three net positioning of the both sides of the steel mesh 1 downwards
