New description: [New technical field] This creation is about the electrode structure of a capping machine, especially the capping process suitable for optical communication components, and can improve the precision of the cap and reduce the beam bias. The amount of electrode structure is shifted. [Prior Art] 丨 Due to the rapid progress of optical communication networks, the required transmission rate in the future will exceed 10 Gbps per channel. Even at such high transmission rates, even relatively small dispersion factors or optical coupling losses are possible. As a result, as the era of comprehensive optical communication networks gradually rises, the laser transmitter/receiver based on optical communication will become an important key to affect the speed and quality of network transmission. Semiconductor lasers currently available as optical communication sources can be broadly classified into three categories: (1) Fabry-Per〇t (FP) semiconductor lasers, (2) single-frequency semiconductor lasers (DFB lasers), and (3) verticals. Resonant cavity surface type laser (VCSEL). (1) Fabry-Per〇t (FP) semiconductor laser: F_p laser uses the end face to provide feedback. The length of the laser cavity allows multiple modes (wavelengths) to exist simultaneously. This multimode laser light is There is a dispersion effect in the transmission of the optical fiber, and there is a limit to the speed and distance of the transmission wheel. However, since the laser structure is relatively simple, the process is relatively easy. (2) Single-frequency laser (DFB laser): In order to overcome the lack and limitation of FP laser, the optical thumb can be used to select a specific wavelength to generate feedback, so that the laser cavity can only resonate at a single wavelength to form a single-frequency laser. Shoot, such as distributed back to 3 M368183 fed single-frequency laser (DFB laser). (3) Vertical cavity surface-emitting laser (VCSEL): vertical cavity surface emitting laser in terms of optical communication systems, optical contact and parallel optical signal effects > due to low critical current Single-mode operation, low beam divergence and the ability to effectively couple single-mode fiber, easy process and long life make VCSEL's future vision promising. In a typical optical communication component used as a laser transmitter/receiver, 'there are usually several main components, such as a header, at least one laser (or received light) disposed on the base. A chip, a cap sealed on the pedestal, and a plurality of pins (Stems) for electrically connecting to the outside. In the manufacture of optical communication components, one of the steps would require sealing the cover to the base on which the wafer has been placed. At present, the common packaging method is to place a cover and a base of the optical communication component on the recesses of the two electrodes, and then combine the two electrodes to make the cover contact with the base, and then add the electrical surface. Micro, shouted the purpose of sealing the seal to the base. In the current technology, the recessed 用以 容 敎 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四The cover card is in the concave f-slip cover operation, or the cover table after the cover is closed, and the cracking does not meet the shortcomings of the helium leak test standard. Fine, the inner diameter of the groove is larger than the outer diameter of the cover, but it also causes the precision of the cover to be inaccurate, and the center offset of the lens or the lens on the cover to the cover is enlarged. , causing the deflection of its laser beam, and needs further improvement. M368183 In view of this, the present invention provides an electrode structure of a capping machine, which utilizes: a positioning mechanism to position the cover of the electrode recess without using a light-sealing machine (4) ve align_ _ 岣 Kodak _ the lens of the ship The beam offset to the center of the pedestal is controlled to be less than the error amount less than ι〇_, and the accuracy of the optical communication component cover is further improved to achieve a faster cover and reduce the non-performing rate of the cover. . [New content] The purpose of the present invention is to provide an electrode structure of a capping machine, wherein a cover body is positioned at a fixed position of a first electrode by a positioning mechanism for providing a base seal Cover, * can achieve the purpose of error and high precision and quick cover. For the above purposes, the electrode structure of a capping machine of the present invention is suitable for a capping process in which an I body is capped on a pedestal. The electrode junction f includes: - a first electrode, a positioning clamp, and a - second electrode. The cover system is the same shape and is placed at the center of the first electrode. One of the openings is open inside and the left and the closed hole are left with _ presets which are difficult to process and then take $. At least a clamping mechanism is disposed at a predetermined position on the first electrode, and the cover body is positioned at the IU position of the Kaixian. The base is clamped by the positioning tongs so that the center point of the base and the center of the cover are positioned on the same-center, the axis, and simultaneously over the opening. The second electrode cooperates with the first electrode to press the cover body and the base corresponding to each other, and the first and second electrodes are input with a predetermined current to electrically weld the cover body and the base to each other. . M368183 In this creation, the implementation of the shot, the positioning of the iron, and the cover system is "sucking ~ magnetic ¥ magnetic material shell, can be hunted by the magnetic attraction of the magnet to adsorb the body in the fixed position of the opening In another embodiment of the present invention, the positioning mechanism includes: a spring=and a spine. The spring is elastically urged against the roller, so that the button is elastically abutted by the ball. At a fixed position on the inner edge of the opening. In another embodiment of the present invention, the positioning mechanism comprises: - an elastic spring ' and elastically protrudes toward the center of the opening with a convex end, The protruding end is abutted against the fixed position of the cover body on the test piece. In another embodiment of the present invention, the positioning mechanism includes: a spring and a cone (four). The miscellaneous contact piece connected to the spring is elastically attached to the top end of the cover body by a cover shape, and the cover body is positioned at a fixed position in the opening by using an inclined surface on the tapered disc. [Embodiment] In order to more clearly describe the electrode structure of the capping machine proposed by the present invention, Please refer to Figure 1 and Figure 2 for the electrode structure of the creation capping machine. The electrode structure 1 is suitable for the capping process of an optical communication component 2. The electrode structure i includes a first An electrode 11, a positioning tong 12, and a second electrode 13. The optical communication component 2 includes a cover 21 and a pedestal 22. The first electrode 11 is provided with an opening 111 at the center thereof. At least one positioning mechanism η] is disposed at a predetermined position on the side of the opening M368183 111. The cover 21 is cylindrical and has an opening σ 211, and the top end of the cover 21 is placed on the first electrode u The opening 211 of the cover body 21 is in an open state in the opening U1. The size of the opening 111 is slightly larger than the cover body 21, so that when the cover body 21 is placed in the opening hole hi, A gap is left between the outer periphery of the cover 21 and the inner periphery of the opening to protect the cover 21 so that the cover 21 can be easily inserted or removed from the opening m. However, the center point 210 of the cover 21 cannot be closed by each person. During the operation, it falls on the central axis 11〇 of one of the openings 1: L1, so that the base 22 and the cover 21 are covered. There is an error in the positioning, and the error of the beam offset caused by the optical communication component 2 is increased, which leads to a significant increase in the defect rate of the finished product. Therefore, the present invention is provided on the first electrode 11 The positioning mechanism 112 applies a predetermined external force to the cover body 21, and thus the cover body 21 is clamped at a fixed position in the opening 111. That is, the clamping mechanism 112 is used to preset suction or push. The squeezing force abuts and fixes the cover body on a part of the inner edge of the opening 111, so that the body is arranged in an eccentric state in the opening of the opening. At this time, the center point 21 of the cover body 21 is detached. Opening the central axis 110 of the hole πι, and further, the maximum width of the gap between the opening 11]L and the cover 21 is substantially concentrated on the other side of the inner edge of the opening iU against which the cover 21 abuts, so that the two There is still a certain margin between the gaps, so that the cover body 21 can be smoothly taken out after the capping operation is completed, and there is no rupture of the cover body 21. The pedestal 22 is respectively clamped on both sides of the pedestal 22 by a missing portion 121 of the two positioning sweet 12 front ends, so that the susceptor 22 is moved to the first electrode 11 disposed at the fixed point M368183 (this time The center point 210 of the cover body 21 is positioned at a fixed position in the opening 111, and the coordinate mark of the movement of the clamping clamp 12 is further adjusted and corrected, so that the center point 220 of the base 22 and the cover body 21 are The center point 210 is overlapped on the same central axis 3 and covers the opening 211 of the δ 盍 body 21. And, each time the optical communication component 2 is covered, the pedestal 22 can use the displacement coordinate base after the first correction positioning as the next time to quickly position the susceptor 22 to the central axis 3 Therefore, the cover speed of the cover 21 and the base 22 is accelerated, and the beam offset error generated by the optical communication component 2 in the cover process is reduced. The second electrode 13 is coupled to the first electrode 11 to press the lid 21 and the susceptor 22 to each other, thereby performing a capping process of the optical communication element 2. The cover body 21 and the base 22 are electrically welded to each other and integrated into one body by inputting a predetermined current to the first electrode 11 and the second electrode 13. The optical communication component 2 can also be one of a light detecting diode or a laser diode. A mirror 212' is disposed at a corresponding top end of the opening 211 of the cover 21 and corresponds to one of the electronic components 221 provided on the base 22. The electronic component 221 on the pedestal 22 penetrates and covers the inside of the cover 21 through the opening 211, and projects or receives an optical signal through the lens 212, and the lens 212 and the electronic component 221 The system is located approximately on the same-center axis 3. The other side of the pedestal 22 is provided with a plurality of pins 222' respectively penetrating the susceptor 22 and electrically connected to the electronic component 221. When the cover body 21 and the susceptor 22 are capped, the susceptor 22 on the second electrode M368183 12 is longitudinally pressed and combined with the mortise body 21 on the first and the eleventh portions. The body 21 and the base 22 are pressed and combined with each other to form a body. At this time, the 'pin 222 extends into the center of the second electrode 13 to define a recess, so that the first electrode H and the second electrode 12 press the cover squid to the base 22 The recess 131 can accommodate the pin 222, and further protect the pin 222 from deformation damage. The cover body 21 and the base 22 are pressed and welded to each other through the first electrode and the second electrode 13 , that is, the opening 2 of the cover 21 passes through the base 22 to close the electronic component 221 to the cover 21 .

The electronic component 221 can be one of a photodiode or a laser diode. In the first preferred embodiment of the present invention, the positioning mechanism 112 includes at least one magnet, and the cover 21 is made of a magnetically permeable material such as iron or the like. The positioning mechanism 112 (that is, the "magnet") is disposed around the opening 111 of the first electrode 11 and is located in a receiving groove 113 of the first electrode u. The receiving groove 113 is from the first - the side of one side of the electrode u extends toward the opening ill' and the positioning mechanism 112 (magnet) is located in the accommodating groove 1B closer to the end of the opening 11; 1. The magnetic property of the positioning mechanism 112 (magnet) itself The cover 21 made of a magnetically permeable material is attracted and positioned at a fixed position in the opening hi. Thereby, when the cover processing of the optical communication component 2 is performed, the center point 210 of the cover 21 is positioned at After the M368183 is adsorbed by the positioning mechanism 112 (magnet), it will deviate from the central axis 110 of the opening 111, so that the center point 210 on the cover 21 can be accurately located at a fixed position in the opening m each time. Therefore, the cover 21 can not only have the margin of taking out or being placed in the opening u of the first electrode 11 but can further control the precision of the cover processing of the optical communication component 2. By fine-tuning Moving the center point 220 of the base 22 clamped on the positioning clamp 12 to The center point 210 of the cover 21 is located on the same central axis 3, so that the lens 212 on the cover 21 and the electronic component 221 on the base 22 substantially overlap the same central axis 3' to complete the light. The communication component 2 is corrected in position of the susceptor 22 in the capping process, and becomes the reference of the position of the susceptor 22 next time. Thereafter, the positioning tong is performed every time the optical communication component 2 is capped and processed. 12, the base 22 can be quickly brought to the correct position of the central axis 3 of the cover body 21, and the base 22 and the cover 21 can be further welded through the second electrode 13 to ensure the mother. Once the cover body 21 and the base 22 are combined with each other, the precision can be less than 10/zm, and the minimum beam offset is achieved. The same electrode structure 1 of the present capping machine is applied to the light detecting diode. During the packaging process, the cover 21 and the pedestal 22 of the photodetector diode can be controlled by the positioning mechanism 112 disposed on the first electrode 11 to control the error of the capping accuracy to 10/. Below zm, further illuminating the light-detecting diode Responsivity and sensitivity are optimized.
