Description

A kind of PCB is to bit combination fixed frame

Technical field

The utility model relates to circuit board manufacture fields, more particularly to a kind of PCB to bit combination fixed frame.

Background technique

To prevent single PCB edge because needing to beat film aligning hole, and when one layer of 3M mono-/bis-of upper face paste faces position gummed paper, Because registration holes rubberizing paper is everywhere within effective form wire, and when tearing the film after exposed, it is easy to cause due to exerting oneself excessive There is the abnormal phenomenon that plate face ink is pullled, and the continuous promotion with market to PCB product quality requirements, client do not connect There is ink by finished product plate face and edges of boards the bad orders such as to fall off, the combo box of the small pcb board design of this heavy industry is mainly exactly to solve This is abnormal bad and specially designs,

There is this to design, the bad defect of ink appearance would not be occurred by aligning processing heavy industry board for anti-welding procedue, thus Good improvement can be played for improving quality.

Utility model content

To achieve the above objectives, the present invention adopts the following technical solutions: a kind of PCB is to bit combination fixed frame, it is special Sign is: including a panel and a bottom plate, the panel bottom is Nian Jie with bottom base plate, and the panel detachably connects with bottom plate It connects, the panel is rectangular box, and the panel has an accommodating space.

Further, the bottom plate offers convenient hole, and the convenient hole is empty along accommodating is contained in perpendicular to panel direction In.

Further, four angles of the panel offer fixation hole, and four angles of the bottom plate offer lower fixed hole, on Fixation hole size and lower fixed hole are in the same size, and upper fixation hole position and lower fixed hole position are arranged in a one-to-one correspondence.

Further, the panel and bottom plate profile are in the same size.

Further, the convenient hole is round or oval.

Preferably, the convenient hole is circle.

Further, the convenient hole edge is included in accommodating space perpendicular to panel upper surface direction.

Artificial contraposition single side exposure operation mode is taken in anti-welding exposure process, and is made in conjunction with aligning clamp Industry.Small pcb board is stored in inside accommodating space, by cementation laminated above and below panel and bottom plate, is finally using corresponding heavy industry material Number anti-welding alignment film contraposition, during contraposition, by original film tape registration holes directly beat molding periphery, Its surrounding technique border region for being adhered to combo box, while can also reduce and fall oily bad, use caused by ink adhesive tape After contraposition combo box is operated, falling oily bad defect and can also prevent completely originally, and effective quality can be carried out Improve.

The utility model is convenient for the dedicated to bit combination fixed frame of contraposition personnel's operation formulation, using single side exposure side Formula, and in the accommodating space for combining contraposition combo box that pcb board is stored in combination fixed frame, post film alignment later i.e. Operation can be directly exposed.

During contraposition, original film registration holes of taping directly are beaten in periphery, are adhered to combination fixed frame Surrounding technique border region, at the same can also reduce fall caused by ink adhesive tape oil it is bad, using contraposition combo box grasped After work, falling the bad defect of oil and can also prevent completely originally, and effective quality improving can be carried out

The utility model has the following beneficial effects: improving production efficiency, avoids generating bad defect, it is anti-welding to improve pcb board face Layer ink falls off bad and asterism dew copper problem.

Detailed description of the invention

The utility model is described in further detail for attached drawing, but the embodiment in attached drawing is not constituted to any of the utility model Limitation.

Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.

It should be noted that it can be directly another when element is referred to as " being fixed on " or " being set to " another element On one element or it may be simultaneously present centering elements.When an element is known as " being connected to " another element, it can To be directly to another element or may be simultaneously present centering elements.

In the present invention, in the absence of explanation to the contrary, the positional terms used such as " upper and lower, left and right " are logical Refer to it is as shown in Figure 1 up and down." inside and outside " refer in specific profile it is interior with it is outer." remote, close " refers to relative to some Component it is remote with it is close.

As shown in figs. 1-4, a kind of PCB that an embodiment of the present invention provides can generally use bit combination fixed frame In common 7KW hand to exposure machine.

As shown in Figure 2, the long and short direction width of the panel 11 is uniformly set as 3cm, on 11 4 its sides of angular distance of panel It is bored respectively at edge 1cm there are four the upper fixation hole 13 that diameter is 3.2mm, 12 size of accommodating space is less than or equal to small pcb board 31 Small pcb board 31 is placed in accommodating space 12 by size.

As shown in Figure 3, the long and short direction width of the bottom plate 21 is uniformly set as 3cm, and bottom plate 21 opens that there are four convenient holes 22 and four lower fixed holes 23, bore that there are four the lower fixations that diameter is 3.2mm respectively at 21 4 its edge of angular distance 1cm of bottom plate Hole 23.

As shown in figs. 1 and 4, panel 11 is secured together with bottom plate 21 with adhered by double sided plaster, convenient 22 center of hole away from 12 edge 3CM of accommodating space, convenient hole 22 are included in accommodating space 12 along the direction perpendicular to 11 upper surface of panel, convenient hole 22 diameters are the through-hole of 2CM, are mainly aligned convenient for operator, and upper 13 position of fixation hole and 23 position of lower fixed hole one are a pair of It answers, upper 13 size of fixation hole and lower fixed hole 23 are in the same size.

As shown in figs. 1-4, artificial contraposition single side exposure operation mode, and combination pair are taken in anti-welding exposure process Position fixture carries out operation.Small pcb board 31 is stored in the inside of accommodating space 12, by about 21 cementation laminated of panel 11 and bottom plate, It finally aligns using the anti-welding alignment film of corresponding heavy industry item number, during contraposition, original film is taped pair Position hole is directly beaten in molding periphery, is adhered to the surrounding technique border region of combo box, while can also reduce ink adhesive tape It is caused fall oil it is bad, after being operated using contraposition combo box, falling oily bad defect and can also prevent completely originally, And effective quality improving can be carried out.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
