Problems solved by technology

Because parallel seam welding has the characteristics of high efficiency, high air tightness, and good welding appearance, it is widely used in mass production, but because some special-shaped structure packaging shells are not suitable for parallel seam welding and energy storage welding, they used to use The laser sealing welding process is used for packaging, and the sealing of the product is difficult to meet the requirements of GJB548, and the weld seam is rough and the appearance is very ugly.

Embodiment Construction

[0024] Such as Figure 3-2 As shown, first fine-tune the X and Y direction knobs of the sealing and welding mold 6 to ensure that the front, rear, left, and right are completely symmetrical, that is, the center of the product, the center of the mold, and the center of the line connecting the two welding wheels are absolutely coincident, and the track is preset at 96-99 (0.096 ~0.099 inches); Then open a groove 7 with a width of 2 mm and a depth of 2 mm at the position where the axle 4 of the sealing welding electrode wheel bears against the lead wire 1, so that the end of the lead wire is in the groove shape; finally, the fine-tuning track is set to 100-103 (ie 0.100 to 0.103 inches), the outer edge of the sealing surface 5 is used for sealing and welding, which can avoid the "ears" 3, and weld the cover plate 2, the base and the "ears" 3 together.

[0025] When packaging, the product must be placed in the center of the mold according to the process requirements. The cover pla...

Abstract

The invention provides a parallel seam welding process and a parallel seam welding apparatus of a special-shaped structure packaging housing. The parallel seam welding process is characterized in that the special-shaped structure housing which is originally processed in the manner of laser seaming is changed to be packaged by utilizing a parallel seam welding process for the first time by the means of improvements and tests that a welding wheel is machined and improved, a seal welding die is precisely adjusted, and the rail configuration of a welded wheel rail exceeds a limit and the like, thereby guaranteeing appearance, sealing property and other various indexes. According to the invention, the basic seal welding requirement is met, and the good appearance and the excellent sealing property are realized, so that the quality and the long-term reliability of a product are greatly improved.

Description

technical field [0001] The invention relates to the hermetic sealing and welding of a hybrid integrated circuit metal casing, in particular to the parallel seam welding of a special-shaped structure packaging casing in the field of packaging technology. Background technique [0002] The batching of integrated circuit design and manufacturing puts forward high requirements on the post-processing technology of devices. Especially in the hermetic sealing welding, not only need to have good airtightness, high welding efficiency, but also put forward new requirements for the appearance of the device; for the hermetic sealing welding of the device, it is widely used at present Laser seal welding, stored energy welding and parallel seam welding. Among them, energy storage welding and parallel seam welding are high-efficiency welding technologies, and parallel seam welding has better welding air tightness than energy storage welding, and is better than laser welding in terms of wel...
