- the present invention relates to the field of soldering technology for mobile communication devices, and more particularly to a microwave device soldering substrate and a microwave device using the microwave device to solder the substrate.
- microwave devices are often used in the field of microwave communication technology. Especially for the field of communication, the stability of the electrical performance of microwave devices is very important.
- Microwave devices require the use of external cables, but due to the need for the selection of existing microwave devices.
- the commonly used material is aluminum alloy, and the aluminum alloy itself cannot be soldered directly to the cable through solder. Therefore, it is often necessary to perform overall plating on the microwave device before soldering, but since the plating of the entire device itself is costly, and The parts that need to be welded are only a small part, so the cost is too high.
- solderable conductor can be soldered to the non-corrodible base.
- the technique disclosed in the patent is a coating process to spray a layer of copper (copper) in an aluminum welded base weld.
- the copper substrate is relatively strong after soldering between the aluminum substrate and the coaxial cable, its vibration resistance and tensile strength are still weak, and the solder joint is subjected to large vibration or the coaxial cable is pulled hard.
- the coaxial cable is easy to carry solder (ie, solder) from the soldering groove of the soldering substrate.
- the traditional welding scheme is not strong, the reliability is poor, there is a safety hazard, and the electrical performance index of the microwave device cannot be guaranteed.
- the purpose of the present invention is to solve the problem that the welding method of the welding method of the microwave device in the prior art is not strong,
- the technical problem that the solder is easy to fall off provides a microwave device and a soldering base thereof which have a simple structure and improve the reliability of the connection between the solder substrate and the soldered member.
- a microwave device welding substrate comprising a cavity and a soldering groove disposed on the cavity, the inner side wall of the soldering groove is provided with at least one soldering space, and the soldering space is opposite to the inner side of the soldering groove
- the direction of the angle is extended so that the solder (for example, solder) is solidified to form a physical interference structure with the soldering groove, which restricts the movement of the solder relative to the soldering groove, thereby preventing the solder and the soldered member from falling off the soldering groove.
- the at least one tin-receiving space is uniformly or discretely disposed inside the welding groove.
- the welding groove is distributed with a plurality of the tin-receiving spaces on the same cross section.
- the tin-storing spaces are correspondingly disposed at positions at the same height of a pair of opposite sides of the welding groove.
- the distance between every two adjacent tin-filled spaces on the same cross-section is equal.
- the tin-storage space is disposed at the intersection of the side and the bottom of the weld groove.
- the tin-receiving space includes a groove disposed on a side of the welding groove.
- the sides of the welding groove are unevenly disposed to form the groove.
- the tin-receiving space comprises a through hole penetrating the side of the welding groove and/or a blind hole opening from the inner side of the welding groove on the side of the welding groove.
- the microwave device welding substrate is integrally formed by a pultrusion or die casting process.
