Description

Molding assembly, camera module, molding assembly splicing plate and manufacturing method

Technical Field

The invention relates to the field of molding, in particular to a molding component, a camera module, a molded component spliced plate and a manufacturing method, which are suitable for an automatic zooming camera module and can reduce the reject ratio.

Background

With the development of the camera module industry, common camera modules in the market are classified into a fixed focus camera module (FF) and an auto zoom camera module (AF). Conventional auto-zoom camera modules typically achieve zooming by an actuator, such as a motor, which requires the actuator to be electrically connected to the circuit board. Therefore, the circuit board of the conventional automatic zoom camera module is specially reserved with a pad area for electrically connecting with an actuator such as a motor.

As the camera module industry is more and more tending to develop miniaturization, manufacturers will use a molding process to minimize the size of the camera module, such as MOC process or MOB process. The capacitor at the edge of the circuit board, even the edge part of the photosensitive chip, is coated by a molding mirror base, thereby realizing the purposes of increasing the strength of the circuit board and reducing the size of the circuit board. When the molding process is applied to the automatic zooming camera module, the molding area needs to avoid the pad area, and the molding material is prevented from covering the pad area, so that the motor can be electrically connected with the circuit board.

A problem that follows is that, as shown in fig. 1, the reserved pad area 11A of the prior art is provided in a square shape, that is, the corner of the molding area 12A is provided with a concave apex 121A that is concave at a right angle for fitting and forming the pad area 11A. Correspondingly, the molding fluid needs to continuously make a right-angle turn at the concave vertex angle 121A to avoid, which causes the molding fluid to flow back, flow rate unevenness and the like, and is difficult to control.

In addition, the boundary of the square pad region 11A blocks the molding fluid. The molding channel formed between the adjacent pad regions 11A may be under-molded due to the blockage of the pad regions 11A. For the MOC process, the molding material encapsulates electronic components such as capacitors and gold wires which are positioned at the edge of the circuit board, and molding fluid with uneven speed can impact the gold wires, the capacitors and the like, so that poor contact of the electronic components is caused.

As shown in fig. 2 to 24, the present invention provides a molded component, a camera module and a molded component panel, which are redesigned in the area of the pad to reduce the defect rate of the auto focus module (AF) production.

A molding assembly 100 in accordance with a preferred embodiment of the present invention is shown in fig. 2 and 3. The molding assembly 100 includes a circuit board 110 and a molding part 120, wherein the molding part 120 is integrally molded with the circuit board 110 to define a light window 130 for forming a photosensitive path.

Specifically, the circuit board 110 has a molding region 111, a mounting region 112 and at least two pad regions 113, wherein the molding region 111 surrounds the mounting region 112 in a closed manner, the pad regions 113 are disposed at corners of the circuit board 110 and located at outer sides of corresponding corners of the molding region 111, and at least two pad regions 113 are respectively used for electrically connecting positive and negative electrodes of an actuator.

The present invention is illustrated by taking the two pad regions 113 as an example, and is not limited thereto. Those skilled in the art will appreciate that more than two of the pad regions 113 may be used and designed as desired. For convenience of illustration and distinction, the two pad regions 113 are respectively referred to as a first pad region 113 'and a second pad region 113", wherein the characteristics of the first pad region 113' and the second pad region 113" may be mutually applicable, and the description of the present invention is omitted.

During molding, the molding region 111 is covered with a molding fluid, and the molding portion 120 is formed after curing. That is, the molding part 120 covers the molding region 111, closely surrounding the mounting region 112. The mounting area 112 is not covered by the molding fluid, and provides space for mounting the photosensitive element 140 and/or the at least one electronic component 150. For different molding processes, as shown in fig. 23 and 24, the components mounted on the mounting region 112 may be different, for example, for MOC process, the photosensitive element 140 is electrically connected to the mounting region 112, and the edge region is located on the molding region 111, so that the cured molding part 120 is molded on the edge region of the photosensitive element 140; for the MOB process, for example, the photosensitive element 140 is electrically connected to be attached to the mounting region 112, and the electronic component 150 is mounted to the molding region 111, so that the cured molding part 120 encapsulates the electronic component 150.

The first pad area 113 'and the second pad area 113 ″ are mirror images, and are not covered by molding fluid, so as to form a first welding space 160' and a second pad area 160 ″ for electrically connecting actuators such as a motor, thereby assembling and manufacturing the automatic zoom camera module. That is, during molding, a molding fluid circulates to avoid the first land area 113', the second land area 113 ″ and the mounting area 112, thereby forming the molding part 120. The first and second bonding spaces 160 'and 160 ″ are formed at the outer corners of the molding part 120 to correspond to the first and

second pad regions

113' and 113 ″ respectively.

In a preferred embodiment of the present invention, the first pad area 113 'and the second pad area 113 "are implemented in a triangular shape, and correspondingly, the first soldering space 160' and the second pad area 160" extend upward from the circuit board 110, as shown in fig. 2 and 3.

The triangular first pad region 113 'has two first outer sides 1131', 1132 'and a first avoiding boundary side 1133', wherein the first outer sides 1131', 1132' and the first avoiding boundary side 1133 'form the first pad region 113' in an end-to-end manner. Since the first pad region 113' is disposed at a corner of the circuit board 110, the two first outer sides 1131', 1132' are implemented as adjacent sides of a top corner of the circuit board 110. The first avoidance boundary 1133 'coincides with a boundary of the molding region 111, that is, the first pad region 113' forms the first avoidance boundary 1133 'on the molding side (the side in contact with the molding region 111) to separate and define the first pad region 113' and the molding region 111.

Correspondingly, the second pad region 113 "of the triangle is formed by two second outer sides 1131", 1132 "and a second avoiding boundary edge 1133" in an end-to-end connection, wherein the two second outer sides 1131", 1132" are implemented as adjacent edges of the top corner of the circuit board 110, and wherein the second avoiding boundary edge 1133 "is also part of the boundary of the molding region 111 for separating and defining the second pad region 113" and the molding region 111. The second, non-overlapping dividing edge 1133 "is also located on the molding side of the second pad region 113" and is in contact with the molding region 111.

The first avoidance boundary edge 1133' and the second avoidance boundary edge 1133 ″ form an angle greater than 90 °. In the preferred embodiment, the first and second avoiding boundary edges 1133', 1133 ″ form an angle of 180 °, i.e., are implemented as a straight line, and are thus obliquely formed at corresponding corners of the circuit board 110.

During molding, the molding fluid needs to flow along the inclined evacuation boundary 1133 'to evacuate the first land area 113' within the area defined by the molding area 111. Compared with a square right-angle design, the inclined first avoiding boundary edge 1133' and the second avoiding boundary edge 1133 ″ have less obstruction to the molding fluid, so that the molding fluid can flow in sufficiently. Meanwhile, the increase amplitude of the flowing speed of the molding fluid is reduced, and the condition of uneven flow speed is lightened. Particularly, in the MOC or MOB process, the molding fluid needs to pass through the electronic component 150, the variation range of the flow velocity of the molding fluid is reduced, the impact on the electronic component 150 such as the encapsulated capacitor and the gold wire is reduced, and the situation that the electronic component 150 is not in good contact is avoided.

Compared with the square right-angle design, the runners correspondingly formed during molding are not continuous right-angle size abrupt changes, but respectively correspond to the first avoiding boundary edge 1133' and the second avoiding boundary edge 1133 ″ to form inclined first buffer runners and second buffer runners. The molding fluid flows along the angled first buffer channel and the second buffer channel, and can accommodate changes in channel dimensions without the need for continuous right angle turns, and with reduced likelihood of mold fluid splashing, backflow, or flow rate non-uniformity.

Furthermore, the first and second bypass boundary edges 1133', 1133 ″ are spaced a greater minimum distance from the inner edge 1111 of the molding region 111 than the prior art square design, for the same area. The specific explanation conforms to the basic common general knowledge of mathematics, and under the same area, the boundary sides of the square pad regions form right-angle projections, but in the preferred embodiment of the invention, the triangular first pad regions 113 'disperse the right-angle regions of the square pad regions, so that the distance between the vertex point 11111 of the first inner edge and the first avoiding boundary side 1133' is larger.

As shown in fig. 3, in the preferred embodiment of the present invention, the first pad area 113' and the second pad area 113 ″ having a triangular shape are formed on the mounting side of a connector 114, and are respectively disposed at both corners of the mounting side of the connector 114.

At this time, the first pad area 113 'and the second pad area 113 ″ are located on the same side, and a pad area side flow path is formed between the first pad area 113' and the second pad area 113 ″ during molding. The flow of the molding fluid into and out of the land area side runner needs to escape the first land area 113' and the second land area 113 ″ from both sides, respectively. Due to the existence of the first avoiding boundary 1133' and the second avoiding boundary 1133", the limitation of the molding fluid flowing into and out of the flow channel on the side of the pad area is reduced compared with the prior art, so that the poor injection molding occurs on the molding part 120 formed on the surface of the flow channel on the side of the pad area.

That is, the design of the present invention accommodates the trend toward smaller camera modules without affecting the molding process and the formation of the molded part. The prior art achieves miniaturization by reducing the size of the runner, or the size of the narrowest part of the molding part, but this affects the flow of molding fluid into and out of the runner on the land area side, and affects the formation of the molding part. The invention meets the miniaturization trend of the camera module group without influencing the molding process and the formation of the molding part by redesigning the pad area.

In actual production, in order to realize miniaturization of the camera module, the narrowest size of the flow channel on the side of the pad area or the molding part is 0.1mm, and the flow of molding materials is influenced. The design of the invention can make the narrowest dimension of the molding part be 0.15mm, and even the narrowest dimension of the molding part is increased, the whole miniaturization is not influenced.

As shown in FIGS. 4 and 5, to implement the molded component 100 of the preferred embodiment of the present invention, the molded component 100 may be formed by cutting a panel 200 of the preferred embodiment of the molded component. The molded component panel 200 includes a circuit board panel 210 and a one-piece molded portion 220, wherein the one-piece molded portion 220 is integrally formed on the circuit board panel 210 through a molding process.

Circuit board makeup 210 has a plurality of molding region 111, a plurality of installation region 112 and a plurality of main pad region 211, wherein molding region 111 arranges in array in circuit board makeup 210, wherein adjacent molding region 111 borders on, wherein molding region 111 correspondingly encircles installation region 112, wherein the triangle-shaped main pad region 211 corresponds molding region 111 sets up in both length sides of circuit board makeup 210.

During molding, the molding areas 111 are covered by molding fluid, and since the adjacent molding areas 111 are bordered by the molding fluid, the molding fluid is cured after covering all the molding areas 111 to form the connected molding part 220. That is, the integral molding 220 covers all of the molding region 111. The mounting area 112 is not covered by molding fluid and the formed one-piece molding 220 surrounds the mounting area 112. The photo chip 140 is mounted on the mounting region 112, and the connected molding portion 220 defines a light window 130 corresponding to the photo chip 140 for forming a photo path.

The circuit board panel 210 includes a plurality of connectors 114, wherein the connectors 114 are correspondingly disposed on two opposite sides of the circuit board panel 210 to electrically connect corresponding regions. The invention is illustrated with the opposite mounting sides of the connector 114 being the length of the panel 210 and the opposite sides of the connector 114 being wider, but not limited to. The direction along the long extension direction of the circuit board panels 210 is the length direction, and the direction along the wide extension direction of the circuit board panels 210 is the width direction. Correspondingly, the elements are arrayed in a row along the length direction and arrayed in a column along the width direction. This is for convenience of description only and is not limiting.

In order to obtain the molding assembly 100 of the above preferred embodiment, the main pad region 211 is formed at the lengthwise side of the circuit board panel 210, corresponding to the outside of the corner of the mounting side (the side where the connector 114 is mounted) of the molding region 111, so that after cutting, the pad region 113 at the corner of the mounting side of the molding region 111 is formed. In the preferred embodiment, the major pad areas 211 at the two widthwise ends of the molded component panel 200 are right triangles, and the other major pad areas 211 are isosceles triangles separated by a widthwise cut to form two right triangles of the pad areas 113.

After injection of molding fluid from one width end of the molded component panel 200, the molding fluid flows along the lengthwise and widthwise channels defined by the molding region 111. When the molding fluid escapes along the escape boundary of the main pad region 211 (the side in contact with the molding region 111), the obstruction to the molding fluid is small because the escape boundary is inclined. Especially for the runner formed between two adjacent main bonding pad regions 211, the molding fluid can be fully filled, the condition of incomplete injection molding of the splicing plate process is reduced, and the overall yield is improved.

As shown in fig. 6 and 7, the mold 300 used for manufacturing the molded component panels 200 includes an upper mold 310 and a lower mold 320, wherein the upper mold 310 and the lower mold 320 are combined to define a molding space 330, and a fluid molding material is introduced into the molding space 330 to perform molding steps. The molding portion of the mold 300 is the same as a conventional mold except that the bottom surface of the mold 310 of the present invention is in contact with the main pad region 211 to prevent the main pad region 211 from being uncovered and molded, thereby forming the bonding space.

Specifically, the circuit board panel 210 is fixed to the lower mold 320, wherein the upper mold 310 and the lower mold 320 are closed, and the molding space 330 defined by the two corresponds to the molding region 111, so that the fluid molding material forms the integral molding portion 220 integrally molded on the circuit board panel 210 after being cured.

Preferably, a pressing edge is reserved on the periphery of the circuit board jointed board 210 for pressing the upper mold 310, so that the molding space 330 is closed, and leakage of molding material is avoided. After molding, the reserved press-fit edges can be cut away, reducing the overall volume. The stitching edges on the connecting side may not be cut due to the connection of the connectors, as shown in the figures such as fig. 3 and 8. That is, when the pad area of the molding assembly is located at the connection side, a bonding edge is not covered between the two pad areas.

The upper mold 310 further includes a plurality of first bosses 311 corresponding to the mounting regions 112 and a plurality of second bosses 312 corresponding to the main pad regions 211, wherein the first bosses 311 and the second bosses 312 are formed by being protruded from the bottom surface of the upper mold 310. The second protrusion 312 is formed and sized to correspond to the shape and size of the main pad area 211 so as to cover the main pad area 211, preventing the molding fluid from covering the main pad area 211. In the preferred embodiment, the cross-section of the second bump 312 is implemented as a triangle corresponding to the main pad region 211.

The first protrusion 311 covers the mounting region 112, prevents the molding material from contaminating the photosensitive element 140, and forms a plurality of light windows 130. For example, in the MOC process, the photosensitive element 140 and the electronic component 150 may be mounted and then molded, and the bottom surface of the first protruding portion 311 is abutted against the surface of the photosensitive element 140; in the MOB process, the photosensitive element 140 and the electronic component 150 may be molded, and the bottom surface of the first protruding portion 311 abuts against the surface of the circuit board corresponding to the mounting region 112, which is only by way of example and is not limited herein.

Preferably, in order to facilitate the drawing, the sizes of the first protruding portion 311 and the second protruding portion 312 are gradually reduced from top to bottom, so as to reduce the drawing resistance. Correspondingly, the size of the optical window 130 is gradually reduced from top to bottom; the size of the bonding space corresponding to the main pad region 211 is gradually reduced from top to bottom.
