Abstract
The utility model discloses a PCB (Printed Circuit Board) electric heating hot melt machine and a heating head thereof. The hot melt machine comprises the heating head, the heating head comprises an end part used for being contacted with a PCB for heating, and the cross section of the end part is in a flat structure. By adopting the heating head, the pre-locating bonding force between every two PCB layers can be increased, and the dislocation probability between every two layers is lowered.
Description
Technical field
The utility model relates to a kind of process equipment, relates in particular to a kind of PCB electric heating fuse machine and heating head thereof.
Background technology
Pcb board i.e. writing a Chinese character in simplified form of " Printed Circuit Board ", and Chinese is a printed circuit board, claims printed circuit board (PCB), printed substrate again, is the supporter of important electron parts, electronic devices and components, the supplier who is electrically connected.Because it is to adopt electron printing to make, so be called as " printing " circuit board.
PCB can be divided into single sided board, double sided board, the above multi-layer sheet of four laminates and soft board according to its application.Generally speaking, the electronic product function is complicated more, the loop distance is long more, contact pin number is many more, and the required number of plies of PCB is also many more.Two or above PCB veneer by navigation system and adhesive material alternately together and the printed substrate that interconnects by designing requirement of conductive pattern just become four layers, six-layer printed circuit board.As previously mentioned, circuit board factory need carry out jigsaw and handle when the processing multi-layer PCB board, and adopting the electric heating fuse machine that the PCB laminate is carried out pre-contraposition handles, promptly process the pre-determined bit hole at the PCB laminate, produce the pre-determined bit adhesion between each laminate of PCB and make, be beneficial to follow-up each laminate pressing location of carrying out.
Consulting Fig. 1 and Fig. 2, is electric heating fuse machine heating head 10 cross sections and front schematic view that prior art is applied to the pre-contraposition of PCB.The end 11 of prior art PCB fuse machine heating head and pcb board contact area is circular design at present, and promptly the end is cylindrical.
Circular heating head is carrying out mainly there is following problem in the course of processing to the PCB laminate:
For guaranteeing stock utilization, the corner design of general PCB laminate is the smaller the better, but cross section causes the interlayer contact area less for the circular pre-determined bit thermosol point that heating head produced can't be done greatly by the frame size restrictions, produces the interlayer dislocation easily in follow-up pressing process.
The utility model content
The technical problem that the utility model mainly solves provides a kind of PCB electric heating fuse machine and heating head thereof, adopts described heating head can increase pre-determined bit adhesion between the PCB laminate, reduces the probability of interlayer dislocation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of PCB electric heating fuse machine heating head is provided, and described heating head comprises the end that is used for the PCB Contact Heating, and described end cross-sectional is flat-shaped structure.
For solving the problems of the technologies described above, another technical scheme that the utility model adopts is: a kind of PCB electric heating fuse machine is provided, comprises heating head, described heating head comprises the end that is used for the PCB Contact Heating, and described end cross-sectional is flat-shaped structure.
The beneficial effects of the utility model are: the PCB that circular heating head causes that is different from prior art adds the less situation that produces the interlayer dislocation easily in follow-up pressing process of interlayer contact area in man-hour, the utility model heating head changes the zone that the end contacts with pcb board into flat design by traditional circle, be appreciated that under the situation of PCB frame size constancy, the cross section be flat heating head contact with PCB and the zone of generation effect much larger than circular heating head, thereby make the pre-determined bit adhesion between the PCB laminate bigger, the anchor point loaded area is bigger during pressing, reduces the probability of interlayer dislocation.
Owing to increase the heat fusion joint area, reduce the risk of interlayer dislocation, adopt the actual measurement effect of the utility model heating head from the applicant, the wrong scrappage of contraposition generally can descend 18%.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 3 and Fig. 4, the utility model PCB electric heating fuse machine heating head 20 embodiment comprise the end 21 that is used for the PCB Contact Heating, and described end 21 cross sections are flat-shaped structure.
When using described heating head 20, be provided with parallel with PCB frame direction the major axis of flat structure, temperature has been met the requirements of the precalculated position that heating head 20 vertically is pressed into described PCB frame, formed the shape fusion through hole identical, realized the pre-determined bit of PCB laminate with described heating head end cross-sectional.
The PCB that circular heating head causes that is different from prior art adds the less situation that produces the interlayer dislocation easily in follow-up pressing process of interlayer contact area in man-hour, and the utility model heating head 20 changes the zone that end 21 contacts with pcb board into flat design by traditional circle.As shown in Figure 5, under the situation of PCB frame size constancy, the cross section be flat heating head 20 contact with PCB and the zone of generation effect much larger than circular heating head, thereby make the pre-determined bit adhesion between the PCB laminate bigger, the anchor point loaded area is bigger during pressing, reduces the probability of interlayer dislocation.
In one embodiment, described flat-shaped structure is a drum type.Described drum type is circle shape behind symmetry excision two parts circular arc.
And in another embodiment, described flat-shaped structure is a rectangle.
In an embodiment was arranged, described flat-shaped structure was oval.
Also consult Fig. 3 and Fig. 4, the utility model also provides a kind of PCB electric heating fuse machine that adopts above-mentioned heating head 20, comprises heating head 20, and described heating head 20 comprises the end 21 that is used for the PCB Contact Heating, and described end 21 cross sections are flat-shaped structure.
Wherein, described flat-shaped structure is a drum type.
Wherein, described drum type is circle shape behind symmetry excision two parts circular arc.
Wherein, described flat-shaped structure is a rectangle.
Wherein, described flat-shaped structure is oval.
Certainly, the utility model heating head be not limited to above-mentioned shape with its cross section, the end PCB Contact Heating, every flat structure that belongs to contacts with PCB and the zone of generation effect can also can be selected greater than circular heating head.
Owing to increase the heat fusion joint area, reduce the risk of interlayer dislocation, from the applicant adopt the actual measurement effect of the utility model heating head, the wrong scrappage of contraposition generally can descend 18% or more than.
