Abstract
The utility model discloses a screen printing nail bed for a printed circuit board. The screen printing nail bed comprises a mother board, a daughter board and a plurality of positioning nails, wherein the daughter board is superposed on the mother board, a rectangular window is formed in the middle of the daughter board, and the positioning nails are vertically fixed on the mother board opposite to the window. The screen printing nail bed provided by the utility model is simple to manufacture and convenient to operate, can well solve the problem that a circuit inside the board is damaged by ejector pins, can be used on printed circuit boards with different specifications, and saves the processing cost.
Description
Technical field
The utility model relates to the equipment that is used to make multilayer board, especially a kind of silk-screen nail bed that is used for printed circuit board.
Background technology
Along with electronic product towards the fast-developing of high performance, densification with upgrade, in order to meet its development trend, manufacturing technology is more and more high-end as the printed circuit board of carrier, the delivery cycle is shorter and shorter.
Silk-screen is that printed circuit board is finished the process that circuit making back selectivity applies one deck solder resist, and the not oxidation of energy protection circuit prevents solder shorts.It is to circuit board two sides silk-screen that conventional silk-screen is made, and promptly clipsheet at first once toasts, and republishes another side, carries out secondary baking.The used time of processing procedure like this is long, the cost of labor height, and the welding resistance two sides can produce certain aberration because stoving time is different.For head it off, industry has the following method of employing: one is to use two-sided screen printer, once baking behind the good two sides of one-step print, but this method needs expensive machine, cost of manufacture height.The 2nd, make special silk-screen nail bed, get out on the nail bed with every kind of circuit board on corresponding hole, hole, put pin, withstand in the circuit board by the pin top and play a supportive role, put shop bolt again and insert in the hole on the circuit board and open fixation.This nail bed need bore corresponding hole according to the hole on the plank, makes trouble; And a nail bed thimble heads on plank plate face, easily causes circuit in the thimble damage plate, particularly for the sort of more thick and heavy, printed circuit board that wiring is intensive; And this class nail bed can only be applicable to a kind of circuit board of specification.
Summary of the invention
The purpose of this utility model is to propose a kind of problem that can solve thimble damage circuit, makes simple, with low cost and is applicable to the silk-screen nail bed of the printed circuit board of different size.
A kind of silk-screen nail bed that is used for printed circuit board of the present utility model comprises motherboard, daughter board and some locating pins, and this daughter board is superimposed on this motherboard, offers rectangular window at the middle part of this daughter board, this locating pin vertically be fixed in window over against motherboard on.
Preferably, described motherboard and daughter board are made by the FR4 sheet material of no Copper Foil.
Preferably, described locating pin comprises base and is fixed on thimble on this base that this base is by being pasted and fixed on the described motherboard.
Preferably, the base of described locating pin is rectangular, and described thimble is fixed in one of them bight of this base, and the remainder of this base is affixed on the described motherboard through U.S. line is gluing.
Preferably, described locating pin be fixed in described window at least one group of across corner over against described motherboard on.
Preferably, be provided with breach in the inboard of two of described window relative frames.
During use, motherboard and daughter board are fixed on the silk-screen workbench with adhesive tape, again pilot pin is fixed on the circuit board edges of boards on the corresponding motherboard of locating hole on, then, printed circuit board is placed on the nail bed, package locating pin and can begin silk-screen.Behind first of the silk-screen, finger is put into indentation, there and takes out plank, behind the turn-over, packages locating pin second of silk-screen again, the two sides all silk-screen good after again the property baking get final product.Compared with prior art, silk-screen nail bed of the present utility model can solve the problem of circuit in the thimble damage plate, and is easy and simple to handle, and can be used for the printed circuit board of different size, saved processing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cutaway view along A-A line among Fig. 1.
Description of reference numerals: 1-motherboard, 2-daughter board, 2a-window, 2b-breach, 3-locating pin, 3a-base, 3b-thimble, 4-circuit board.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
One of them embodiment of the present utility model as shown in Figure 1, the silk-screen nail bed that is used for printed circuit board mainly also can be for a plurality of by motherboard 1, daughter board 2 and two locating pin 3() form, motherboard 1 and daughter board 2 all adopt the FR4 sheet material of no Copper Foil to make, the size of motherboard 1 and screen printer coupling.Daughter board 2 is superimposed on this motherboard 1, offers rectangular window 2a at the middle part of this daughter board 2.Preferably, be provided with breach 2b in the inboard of two of daughter board 2 relative frames, convenient with hand sense circuit plate 4 when turn-over.Locating pin 3 is made of base 3a and thimble 3b, and base 3a is square stainless steel substrates, and thimble 3b is cylindrical, and it is integrally formed in one of them bight of base 3a.
During use, below motherboard 1 is placed on, again with daughter board 2 overlapping being placed on above the motherboard 1, with adhesive tape both are fixed on the silk-screen workbench then, diagonal position at the window 2a of daughter board 2 is placed a locating pin 3 respectively, and the locating hole on the edge of the thimble 3b that makes locating pin 3 and circuit board 4 is corresponding, so promptly finishes the installation of silk-screen nail bed.Then, printed circuit board 4 is placed on the nail bed, packages locating pin 3 and can begin silk-screen, behind first of the silk-screen, finger is put into breach 2b place taking-up plank, behind the turn-over, packages locating pin 3 second of silk-screen again, the two sides all silk-screen good after again the property baking get final product.
This shows that silk-screen nail bed of the present utility model can be used for the thick and heavy printed circuit board 4(thickness of different size more preferably greater than 4mm), its making is simple, easy to operate, with low cost, can save processing cost; And thimble inserts in the locating hole of circuit board, can not damage circuit in the plate, has solved the problem of circuit in the thimble damage plate well.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
