Abstract
The invention discloses a metal base printed circuit board capable of 360-degree bending, and a manufacturing process thereof. The metal base printed circuit board comprises a metal base printed circuit board body. The metal base printed circuit board body is provided with multiple I-shaped hollow holes. The advantages are as follows: the structure is simple, the multiple I-shaped hollow holes are arranged on the metal base printed circuit board body, fine metal bent ribs are formed respectively at the top portion and the bottom portion of the rectangular-shaped metal base printed circuit board body, and multiple hard circuit boards are formed on a middle portion. In case that bending is needed when the metal base printed circuit board is applied to a special product, the metal bent ribs are bent to drive the circuit boards to be bent, since the circuit boards are connected with the metal bent ribs through splicing points, the internal stress borne by the circuit boards is almost neglected, and after bending, the circuit boards are still in the shape of a straight plate such that the metal base printed circuit board provided is not affected even if being bent by 360 degrees, thus the purpose for the special product can be realized.
Description
[technical field]
The present invention relates to a kind of printed circuit board (PCB), particularly a kind of metal base printed circuit board and manufacture craft thereof that can 360 ° of bendings.
[background technology]
Metal base printed circuit board (Metal Core PCB, MCB) be that original printed circuit board (PCB) is affixed on the better metal of another thermal conduction effect, can improve the heat radiation of circuit board aspect, MCPCB is the one in rigid PCB, because rigid PCB is unfavorable for bending, a rigid PCB is difficult to realize 360 ° of bendings.MCPCB bending is at present only limited to and curves the circle that diameter is larger, use face is smaller, and after bending, can make MCPCB internal stress increase, when after MCPCB Surface Mount Component,, the internal stress that bending produces can produce larger pulling force (tension force) to components and parts, makes Surface Mount component's feet cracking or scolding tin ftracture and cause electric connection to disconnect, simultaneously, in the time that bending angle is excessive, easily cause the copper layer that covers of MCPCB to ftracture, so be difficult to use 360 ° of MCPCB bendings to realize specialities purposes.
[summary of the invention]
The object of the invention is to overcome deficiency of the prior art, a kind of simple in structure, metal base printed circuit board and manufacture craft thereof that can realize 360 ° of bendings is provided.
A kind of metal base printed circuit board that can 360 ° of bendings is provided, and it comprises metal base printed circuit board main body, and described metal base printed circuit board main body is provided with the hollow hole of multiple " work " font.
In said structure, described metal base printed circuit board main body is rectangular configuration, the setting side by side of the hollow hole of described multiple " work " font.
In said structure, metal bending rib is formed respectively on the top of the metal base printed circuit board main body after described hollow out and bottom.
The present invention also provides a kind of manufacture craft of metal base printed circuit board, and this manufacture craft comprises the steps:
(1) processing metal base printed circuit board main body, design according to actual needs circuit and the profile of metal base printed circuit board main body, profile is rectangular flat structure, and its long limit is the circumference of required cylindrical structural body, presses afterwards the machine-shaping of PCB conventional production process;
(2) engrave hole, the hollow hole of hollow out multiple " work " font side by side in metal base printed circuit board main body, makes the top of the metal base printed circuit board main body after hollow out and bottom form respectively metal bending rib;
(3) SMT processing, mounts the assembling of components and parts in the metal base printed circuit board main body after hollow out, adopt conventional SMT explained hereafter;
(4) performance test, carries out electrical property, optical property and hot property to the metal base printed circuit board main body after the upper Surface Mount of step and detects, and detects after qualified and is semi-finished metal base printed circuit board;
(5) bending process, designs processing bending fixture tool according to the diameter of described cylindrical structural body, and semi-finished metal base printed circuit board is bent to Profile procoess along bending fixture tool;
(6) assembling moulding, provides a locker, by locker, the two ends of the semi-finished metal base printed circuit board of bending process moulding is locked to the bending process of complete metal base printed circuit board.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, adopt the hollow hole that multiple " work " font is set in metal base printed circuit board main body, make rectangular-shaped metal base printed circuit board main body top and bottom form respectively tiny metal bending rib, the multiple rigid circuit boards of middle formation, while needing to bend on for specialities, bending metals bending rib two ends, make it drive the bending of avd interval plate, form polygonized structure, because circuit board is connected with metal bending rib by splice point, so the internal stress that circuit board is subject to is almost negligible, after bending, circuit board is appointed and is so plane, even if thereby it is also unaffected to reach 360 ° of bendings, realize the purposes on specialities with this.
