Abstract
The invention provides a coating method of a local additive coating material, which is applicable to various printing circuit boards, in particular to a method used for coating the additive local coating material on circuit blocks after circuit preparation or insulation layer coating are completed on a plurality of circuit blocks of the printing circuit board which is combined softly or hard or both softly and hard; the method comprises the steps as follows: a shaping material which covers a plurality of circuit blocks simultaneously is provided with a coating material; a depth control tool is used to cut the corresponding region to be coated on the circuit blocks and align the position corresponding to the circuit block; subsequently, false coating and pressing are carried out and the shaping material is torn out of the coating material; therefore, the additive coating material can be correctly coated on the prearranged position of the circuit blocks without need of bonding one by one on the circuit blocks; furthermore, the coating is exacter and the working time is saved.
Description
Technical field
The present invention is a kind of method for sticking and covering that is applicable to the local additional sticking material of various printed circuit board (PCB)s; it is after the circuit blocks on the printed circuit board (PCB) is finished circuit making back or is coated with layer of cloth; paste anti-electromagnetic interference (Electromagnetic Interference; abbreviation EMI) sheet metal or protection glued membrane take place to save the situation that can avoid misalignment man-hour again.
Background technology
Rigid printed circuit board is called hardboard again, is that material is carried on the basis of electronic industrial products such as all information, electronics, communication, consumer electronics, space flight and national defence, present design and make towards the small-bore, the direction on high density, multilayer number, fine rule road develops.
Moreover flexible printed wiring board is called soft board (FPC, flexible printed circuit) again, has characteristics such as light weight, thin little, bent, low-voltage, low consumpting power.Because product can change shape according to spatial design, and foldable and prevent electrostatic interference, make the application product volume-diminished, weight significantly alleviates, thus begin to replace traditional hardboard, and be used in commercial uses such as satellite and health care industry.Closely during the last ten years, because of information and consumption electronic products develop rapidly, emphasizing to make the consumption of soft board and quality grow up rapidly under high function, small size, the lightweight demand.Domestic manufacturers are many to produce single face and double sided board at present, mainly supply at mobile computer, mobile phone, LCD, CD-ROM drive, digital camera etc.
Again, the requirement (as mobile phone, LCD) for the density of the area that adapts to the compact product of various differences and circuit often gives soft, rigid printed circuit board in conjunction with using.
No matter the making of printed circuit board (PCB) is rigid; soft or soft; the kenel of rigid combination; often look the size or the arts demand of the circuit blocks of printed circuit board (PCB); and the plurality of circuits block is arranged on the printed circuit board (PCB); and behind the circuit of the intact circuit layer of photolithographic fabrication; avoid the influence of ambient temperature and humidity for preventing copper wire oxidation and protection circuit; and its durability of increase; must be in the top last layer protection glued membrane that adds; maybe must cover the sheet metal of going up anti-electromagnetic interference (EMI); but because of these protect glued membranes very soft, or volume is very little, very is not easy entirely to cover on the circuit blocks; therefore; generally carry out contraposition; overlay program all must be finished individually by block of block of experienced operators, and can't use automation instead; a large amount of production reduces cost.
The inventor further develops out a kind of method for sticking and covering that is applicable to the local additional sticking material of various printed circuit board (PCB)s of the present invention again because the disappearance of above-mentioned method for making when implementing studies intensively.
Summary of the invention
A purpose of the present invention, be to provide a kind of method for sticking and covering that is applicable to the local additional sticking material of various printed circuit board (PCB)s, it mainly is to be provided with the plurality of circuits block in a printed circuit board (PCB), by the coverlay that can contain several circuit blocks areas simultaneously, the zone that desire on several circuit blocks is covered once pastes simultaneously.
Another purpose of the present invention, be on certain section bar, to be provided with a sticking material, after will not cut by degree of depth control tool with the zone that pastes the corresponding position, with its aligned number circuit blocks opposite position, the material of will finalizing the design again tears off in sticking material, so, sticking material is correctly pasted on these circuit blocks precalculated positions, and once aim at circuit blocks more than several, and do not need to paste one by one the situation of not only having saved time but also can exempt misalignment.
The object of the present invention is achieved like this, a kind of method for sticking and covering that is applicable to the local additional sticking material of various printed circuit board (PCB)s, it is to be applied to one be provided with a plurality of circuits of having finished and make or be coated with on the printed circuit board (PCB) of circuit blocks of layer of cloth, and the specific region on these circuit blocks adds sticking material, and this method includes:
The typing material that can contain at least two circuit blocks on this printed circuit board (PCB) in an area, this typing material is provided with a sticking material, again by instrument with on the sticking material not with these block circuit on the corresponding position, specific region cut, and this typing material is provided with more than one corresponding points on ora terminalis;
On the printed circuit board (PCB) certain position, then be provided with the datum mark relative with corresponding points, when pasting, can be with the corresponding datum mark of corresponding points, the sticking material that can contain several circuit blocks again is covered on the specific region, and carrying out vacation subsides and pressing action, the material of will finalizing the design again tears off in sticking material;
From the above mentioned, the present invention can make sticking material correctly paste on these circuit blocks precalculated positions, and once aims at the circuit blocks more than several, and does not need to paste one by one, the situation of not only having saved time but also can exempt misalignment.
