Abstract
The utility model relates to a base plate device for a two-sided silk-screen ultrathin PCB (Printed Circuit Board). The base plate device comprises a workbench, wherein a base plate is arranged on the workbench, a support part is arranged at the outer side of the base plate, a blind groove is formed in the inner side of the base plate, and supports and support columns are arranged in the blind groove. The support part plays a supporting role in a two-sided silk-screen process, so that the PCB are uniform in stress; and the groove turning depth of the blind groove part is one half of the thickness of the base plate, and the blind groove is used for preventing a soldering mask from being damaged to influence the appearance of the board surface and the quality of the PCB because one printed surface is in contact with the base plate in the process of carrying out silk-screen printing on the other surface. According to the utility model, the PCB of which is the thickness is between 0.4m and 0.8mm is put on the base plate device and is then subjected to two-sided silk-screen printing. Compared with the prior art, the base plate device has the advantages of greatly improving the production efficiency and ensuring the quality of the PCB.
Description
[technical field]
The utility model relates to the pallet device of a kind of double-surface screen printing PCB, particularly relates to the pallet device that double-surface screen printing thickness is 0.4mm-0.8mmPCB.
[background technology]
In PCB manufacturing field, greater than the pcb board of 1.0mm during at double-surface screen printing, we adopt the nail bed usually, have avoided the complete one side of silk-screen to carry out baking sheet when thickness of slab, silk-screen continuously, thus saved the production time, improved production efficiency.But.Pcb board for thickness of slab between 0.4mm-0.8mm when carrying out silk-screen on nail bed, often because the thin plate rigidity causes the welding resistance ink silk screen printing inhomogeneous and can't carry out double-surface screen printing not, quality problem easily occurs, delays product and hands over the phase.
[summary of the invention]
It is the pallet device of 0.4mm-0.8mmPCB for double-surface screen printing thickness that the utility model is intended to address the above problem and provide a kind of.
For achieving the above object, it is the pallet device of 0.4mm-0.8mmPCB for double-surface screen printing thickness that the utility model provides a kind of, this pallet device comprises workbench, backing plate is installed on workbench, the described backing plate outside is provided with support, described backing plate inboard is provided with blind slot, is provided with in this blind slot to support and pillar.
The degree of depth of described blind slot is half of plate thickness.
Described backing plate is fixed by a pin on workbench.
Contribution of the present utility model is, described backing plate comprises support section and blind slot part, support section is played a supporting role when double-surface screen printing, make pcb board stressed evenly, the gong groove depth of blind slot part is half of plate thickness, its effect is that the one side of avoiding out of the press when the silk-screen another side is destroyed because of the solder mask that the contact backing plate causes, and affects plate face outward appearance and product quality.The utility model carries out double-surface screen printing by thickness of slab is placed between the pcb board between 0.4mm-0.8mm on this pallet device, compared with prior art, greatly improved production efficiency, has guaranteed the quality of product.
[description of drawings]
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model backing plate front view.
[specific embodiment]
The following example is to further explanation of the present utility model and explanation, and the utility model is not constituted any limitation.
As shown in Figure 1, the utility model comprises workbench 10 and backing plate 20 two parts, and backing plate 20 is fixed on workbench 10 by four shop bolts 11, prevents that backing plate 20 from sliding.
As shown in Figure 1 and Figure 2, described backing plate 20 comprises support 21 and blind slot 22 two parts, and described blind slot 22 is positioned in the middle of backing plate 20, and support 21 is positioned at the outside of backing plate 20, forms bossings around blind slot 22.Support 21 couples of PCB and play a supportive role, make pcb board stressed evenly, with the ink for screen printing inequality of avoiding partly caving in and causing because of pcb board.Blind slot 22 effect is, when the silk-screen another side, due to the support of the support section of this device, pcb board can not contact bottom land, is stained with because of plate face printing ink the plate face quality problem that the bottom land of backing plate causes with regard to not occurring.
As shown in Figure 1 and Figure 2, the degree of depth of described blind slot 22 is half of backing plate 20 thickness, is provided with a plurality of supports 221 and pillar 222 in blind slot 22, and these a plurality of supports 221 are corresponding with pcb board, namely corresponding with non-metallic groove and the PAD position of PCB with pillar 222 positions.
The making step of backing plate 20 of the present utility model: A, the copper-clad plate of getting the FR-4 material are carried out sawing sheet by the sawing sheet size of the pcb board of want silk-screen; B, with the copper-clad plate etching after sawing sheet, remove copper sheet, only keep base material part; C, the substrate after etching is carried out the gong blind slot, be about to the regional gong blind slot corresponding with circuit pack after the pcb board moulding, its gong deep thickness is half of plate thickness, but the position corresponding with the non-metallic groove of PCB finished product and PAD position gong blind slot not wherein, the size in gong groove zone is larger than the size of PCB finished product part.
The action principle of this pallet device: at first, pin 11 on workbench 10 corner locations is used as the location; Then, this backing plate 20 is aimed at locating hole dress plate, and load onto the pcb board 12 of the silk-screen of wanting on backing plate 10; Secondly, carry out silk-screen, silk-screen wherein after one side, refills silk-screen another side on backing plate, last baking sheet.
Although by above embodiment, the utility model is disclosed; but protection domain of the present utility model is not limited to this; do not departing under the condition of the utility model design, the distortion that above each member is done, replacement etc. all will fall in claim scope of the present utility model.
