Abstract
The utility model discloses a supporting block for a PCB. The supporting block comprises one or more supporting units. The supporting unit comprises a pedestal and a soft rubber layer. The bottom of the soft rubber layer is fixed on a top surface of the pedestal, and the top surface is equipped with a plurality of protruding rubber nails. The supporting block for the PCB is convenient for the PCB with an uneven surface to be placed stably, and enables components on the PCB not to be damaged.
Description
Technical field
The utility model relates to a kind of SMT (Surface Mounted Technology, surface mounting technology) process technique, particularly a kind of pcb board back-up block.
Background technology
SMT (Surface Mounted Technology; Surface mounting technology) is most popular a kind of technology and technology in the present electronics assembling industry; It is a kind ofly will not have pin or short leg surface-assembled components and parts and (be called for short SMC/SMD; The sheet components and parts claimed in Chinese) be installed in the surface of PCB (Printed Circuit Board, printed circuit board) plate, through methods such as reflow welding or the immersed solder circuit load technology of welding assembly in addition.
SMT adds can carry out the element paster respectively to first and second of pcb board man-hour; First face of pcb board is carried out the element paster add man-hour; Second to pcb board is supported earlier, refluxes after processing first, in the same way second face is processed.
One Chinese patent application 201010614612.1 discloses a kind of pcb board back-up block, and is as shown in Figure 1, comprises substrate 1, the base 2 that is fixedly connected with substrate 1;
Wherein, Substrate 1 has upper surface 3, lower surface 4, and the upper surface 3 of substrate 1 is a horizontal plane, and the lower surface 4 of substrate 1 is fixedly connected with base 2; Offer the through hole 5 that several run through its upper surface 3 and lower surface 4 on the substrate, through hole 5 is evenly distributed on the substrate 1;
The smooth one side of pcb board is placed on the upper surface 3 of this pcb board back-up block substrate 1, the empty portion 6 of base 2 is carried out negative pressure handle, pcb board is adsorbed on the upper surface 3 through the through hole on the substrate 15; Need not to seek the PIN pin strong point when placing pcb board; Can save pcb board standing time, and avoid PIN to cause damage to the element on the pcb board, pcb board is adsorbed on the upper surface of substrate; Absorption is stable, supporting surface big and flat, and it is stressed evenly to add man-hour each position of pcb board.But add man-hour when pcb board first face carries out need carrying out the element paster to second face after the element paster machines, first of pcb board is just different because surface mount elements is arranged, and this pcb board back-up block can't the stable support pcb board.
The utility model content
The technical problem that the utility model will solve provides a kind of pcb board back-up block, is convenient to stablize the irregular pcb board of placement surface, and can not cause damage to the element on the pcb board.
For solving the problems of the technologies described above, the pcb board back-up block of the utility model comprises one or more support units;
Said support unit comprises a base, a soft rubber layer;
Said soft rubber layer, the bottom surface is fixed on said base top surface, and the rubber tack of a plurality of projections is arranged on the end face.
Said base can be magnetic bases.
The pcb board back-up block can also comprise a base plate;
Said support unit, its base end face is fixed on the said base plate.
Preferable, the pcb board back-up block has six support units, and six support units are divided into two rows and are fixed on the said base plate.
Preferable, the base of each support unit, soft rubber layer are rectangular, are evenly distributed with the rubber tacks of many row's projections on the soft rubber layer end face of rectangle.
The pcb board back-up block of the utility model, in the time of on pcb board being placed on this pcb board back-up block, each support unit supports pcb board through soft rubber tack, need not to seek the PIN pin strong point when placing pcb board, can save pcb board standing time; Because with the pcb board contact is soft rubber tack; Can not cause damage to the surface mount elements on the pcb board; And on the pcb board because surface mount elements is arranged height not simultaneously, the soft rubber tack of this pcb board back-up block can produce corresponding deformation, thereby can the stable support pcb board; Base with magnetic can further strengthen the supporting & stablizing degree to pcb board through magneticaction.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model; Do simple the introduction in the face of the accompanying drawing of the required use of the utility model down; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model.And under the situation of not conflicting, embodiment and the characteristic among the embodiment in the utility model can make up each other.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtained belongs to the scope that the utility model is protected.
Embodiment one
The pcb board back-up block is as shown in Figure 2, comprises one or more support unit 1, a base plate 2;
Said support unit 1 comprises a base 11, a soft rubber layer 12;
Said soft rubber layer 12, bottom surface are fixed on base 11 end faces, and the rubber tack 121 of a plurality of projections is arranged on the end face;
Said one or more support unit 1, its base 11 bottom surfaces are fixed on the said base plate 2;
Preferable, said base is magnetic bases.
Embodiment two
The pcb board back-up block has six support units, and six support units are divided into two rows and are fixed on the base plate, and the base of each support unit, soft rubber layer are rectangular, is evenly distributed with the rubber tacks of many row's projections on the soft rubber layer end face of rectangle.
The pcb board back-up block of the utility model; As shown in Figure 3, when pcb board 3 being placed on this pcb board back-up block, each support unit supports pcb board 3 through soft rubber tack 121; Need not to seek the PIN pin strong point when placing pcb board 3, can save pcb board standing time; Because with pcb board 3 contacts are soft rubber tacks 121; Can not cause damage to the surface mount elements on the pcb board 3 31; And on the pcb board 3 because surface mount elements 31 is arranged height not simultaneously, the soft rubber tack 121 of this pcb board back-up block can produce corresponding deformation, thereby can the stable support pcb board; Base with magnetic can further strengthen the supporting & stablizing degree to pcb board through magneticaction.
