[0002] In the field of optical communications, the main function of an optical transmission module is to convert electrical signals into optical signals and then convert the optical signals back into electrical signals.
[0003] In the information age, the rapid adoption of cloud computing, artificial intelligence, and 5G mobile applications has led to an increasing reliance on robust and ultra-high-speed communications and data center infrastructure. Fiber optic communication technology plays a vital role in the rapid development of this infrastructure. In response to the growth in data rates and interconnection density, the per-channel data rate of optical transceiver modules has increased from 25 Gbps to 100 Gbps, or even higher.
[0004] A growing problem in the prior art is the increasing heat generated by laser diodes during operation. This inefficient heat removal results in reduced laser output power and, most importantly, shorter laser lifetime.
[0005] Therefore, in order to overcome the heat dissipation problem within the allowed space, a Tosa structure is provided, and a heat sink is added. The Tosa structure provides a direct heat path for each signal source and increases the heat dissipation area. Due to the module assembly space and position requirements, the heat sink needs to be pasted in a specific position. During the welding process of the flexible circuit board, the heat sink pasting position of some products will be offset. Utility Model Content
[0006] The utility model aims to provide a TOSA type manual flexible circuit board welding fixture to check whether a heat sink block is offset.

[0009] In a possible implementation, the opening end of the material trough is chamfered.
[0010] In a possible implementation, the material trough includes a base trough and a body trough, the base trough is arranged at the top of the body trough, and the width of the base trough is greater than that of the body trough, so that the opening cross-section of the material trough is T-shaped.

[0028] The TOSA type manual flexible circuit board welding fixture provided by the utility model is now described.
[0029] Please also read Figure 1 The TOSA type manual flexible circuit board welding fixture includes a base plate 1, a fixing part 2, a locking mechanism, a receiving groove 4 and an inspection mechanism, wherein the fixing part 2 is detachably arranged on the base plate 1, and a material groove 101 is arranged on the fixing part 2; the locking mechanism is arranged on the fixing part 2, and the locking mechanism is used to fix the material in the material groove 101; the receiving groove 4 is arranged on one side of the material groove 101, and the material groove 101 is connected to the receiving groove 4, and the receiving groove 4 is used to accommodate the heat dissipation block of the material during welding; the inspection mechanism is arranged on the fixing part 2, and the inspection mechanism is used to detect whether the pasting position of the flexible circuit board is qualified.
[0030] The beneficial effect of the TOSA type manual flexible circuit board welding fixture provided in the present embodiment is as follows: compared with the prior art, the TOSA type manual flexible circuit board welding fixture provided in the present embodiment provides a receiving slot 4 on one side of the material slot 101. When the material is fixed, the heat sink on the material is placed in the receiving slot 4, and the heat sink is limited by the receiving slot 4. Since the heat sink is fixed relative to the material, and a flexible circuit board pasting position is provided on the top of the material, once the pasting position of the heat sink is offset, the position of the flexible circuit board after welding will also be relatively offset relative to the inspection mechanism. In this way, whether the bonding position of the heat sink is qualified can be judged according to the offset of the flexible circuit board relative to the inspection mechanism after welding, thereby improving the qualified rate of the product.
[0031] In this embodiment, the material trough 101 is vertically arranged. The locking mechanism includes a mounting hole and a locking bolt 3. The mounting hole is arranged on the fixing member 2. The axial direction of the mounting hole is arranged horizontally, and the axial direction of the mounting hole is parallel to the open end of the material trough 101. The mounting hole is connected to the material trough 101. The locking bolt 3 is screwed into the mounting hole, and the locking bolt 3 can be rotated so that a part of the locking bolt 3 is extended into the material trough 101. When in use, the material is inserted into the material trough 101, and then the locking bolt 3 is rotated so that the locking bolt 3 is pressed against the material to achieve the purpose of fixing the material.
[0032] As a preferred technical solution, the opening end of the material trough 101 is chamfered, so that when the material is placed into the material trough 101, the edge of the opening end of the material trough 101 will not scratch the material.
[0033] In addition, the material trough 101 includes a base trough 103 and a body trough 102. The base trough 103 is arranged at the top of the body trough 102. The width of the base trough 103 is greater than that of the body trough 102, so that the opening cross section of the material trough 101 is T-shaped. Since the size of the base is slightly larger than the body of the material, such a setting can better fix the material. It is worth noting that the mounting hole is connected to the body trough 102.
[0034] The inspection mechanism includes a flexible circuit board slot 5, which is arranged on one side of the material slot 101 and is connected to the base slot 103. When in use, the flexible circuit board is placed in the flexible circuit board slot 5. After welding, if the flexible circuit board deviates from the flexible circuit board slot 5, the welding is unqualified.
[0035] like Figure 1As shown, the fixing member 2 includes a fixing block 201 and two connecting plates, and the material trough 101, the containing slot 4, the locking mechanism and the containing slot are all arranged on the fixing block 201. The fixing block 201 is in a cube shape, and the connecting plates are arranged on both sides of the fixing block 201. A plurality of first fixing holes 203 are arranged on the connecting plate 202, and a plurality of second fixing holes are arranged on the bottom plate 1. The first fixing holes 203 and the second fixing holes correspond to each other one by one. The bolts pass through the first fixing holes 203 and are screwed into the second fixing holes, so that the fixing member 2 is fixed on the bottom plate 1. The arrangement of the first fixing holes 203 and the second fixing holes can facilitate the fixing member 2 to be detachably arranged on the bottom plate 1.
[0036] Preferably, the vertically arranged corners of the fixing block 201 are chamfered to prevent the edges of the fixing block 201 from scratching the staff.
[0037] Finally, the first fixing hole 203 is a strip hole, which extends along the length direction of the connecting plate 202, and the extension directions of the strip holes are parallel to each other. The arrangement of the strip holes can facilitate fine adjustment of the position of the fixing block 201, making the TOSA type manual flexible circuit board welding fixture of the utility model more convenient to use.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
