Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic packaging, in particular to a new type of ceramic packaging shell and a production device thereof. BACKGROUND

[0002] Traditional dual-in-line package (DIP) shell is a multi-layer DIP type ceramic package with two rows of parallel metal pins. Dual-in-line package (DIP) is one of the plug-in packages, and chip packaging basically adopts DIP packaging. This packaging form has the characteristics of suitable PCB (Printed Circuit Board) through-hole installation, wiring and operation at that time. The pins are led out from both sides of the package, and the package materials are plastic and ceramic. The structure of DIP package is various, including multi-layer ceramic dual-in-line package (DIP), single-layer ceramic dual-in-line package (DIP), and lead frame type DIP. DIP is the most popular plug-in package, and the chips using this packaging method have two rows of pins, which can be directly soldered on the chip socket with DIP structure or in the soldering position with the same number of soldering holes. Its characteristics are that it can be very convenient to realize the through-hole welding of PCB, and it has good compatibility with the mainboard.

[0003] A Chinese invention patent with the authorized publication number CN111599802B discloses a ceramic packaging shell and a packaging shell mounting structure, which comprises a ceramic base, a ceramic insulator, a cover plate and a solder pad structure. The ceramic base is a multi-layer structure and is provided with a cavity. The ceramic insulator is arranged on the ceramic base and has a radio frequency transmission structure penetrating through the side wall of the cavity. The cover plate is arranged on the cavity. The solder pad structure is arranged on the bottom of the ceramic base. The ceramic packaging shell provided by the present application has excellent microwave performance, high-density wiring, high-integration of components and more pins, and can realize high-density interconnection.

[0004] However, the single-row pins of the above-mentioned ceramic packaging shell have fixed pitch, the inner bonding area is directly connected to the side pad through metal paste to form an internal and external conduction structure, which requires that the width of the metal paste cannot exceed the width of the pin pad, and it is difficult to realize the overload current of 50VDC, 40A, conduction time 100ms, and off time 900ms. Since the internal circuit is directly connected, the connection line connected to the pad cannot exceed the size of the pad, and the width of the pin pad is limited, resulting in that the overall line width cannot be too wide, so that the pin resistance is large, and when passing through a high current load, there are problems such as breakdown and burning. In addition, the switching of each station in the production process of the prior art usually needs to be operated manually, and manual labor is required for feeding, assembling and subsequent welding, which has high labor cost and low production efficiency, and the continuity of production is not high. And the prior art needs to manually place the silver-copper soldering sheet on the surface of the ceramic part, and then place the metal cover sheet on the silver-copper soldering sheet and then perform brazing. Since the silver-copper soldering sheet is very thin with a thickness of 0.06-0.1mm, it is difficult to take when placed on the metalized ceramic surface, and there are problems such as missing or less placing when manually placed, and the problems of welding leakage and poor welding caused by the absence of soldering sheet or soldering wire after brazing.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 9 As shown, a novel ceramic encapsulation shell includes a ceramic component 1, a metal cover 2, and pins 3. The ceramic component 1 has an upper lead-out layer 11 and a lower lead-out layer 12 inside. The upper lead-out layer 11 is connected to the lower lead-out layer 12 through a hollow hole 4. The metal cover 2 and pins 3 are respectively encapsulated and soldered to the top and sides of the ceramic component 1. A solder layer 5 is provided between the metal cover 2, pins 3, and ceramic component 1. The hollow hole 4 is filled with tungsten metallization paste. The interior of the ceramic component 1 is divided into an upper lead-out layer 11 and a lower lead-out layer 12. The upper lead-out layer 11 is located above the lower lead-out layer 12. A hollow hole 4 is made on the ceramic component 1 to pass through the upper lead-out layer 11 and the lower lead-out layer 12. The pins 3 that require increased current load are heat-sinked. With sufficient space on the side wall of the ceramic component 1, the internal connecting wires are appropriately widened and connected to the lower lead-out layer 12 by filling the hollow hole 4 with tungsten metallization paste. Then, the wires are connected from the lower lead-out layer 12 to the side metallization pads to form a parallel circuit, thereby reducing the on-resistance while increasing the current load.

[0036] like Figure 9 As shown, ceramic component 1 is made of 92% alumina and is manufactured using a multi-layer alumina ceramic tungsten metallization high-temperature co-firing process. Pin 3 is made of iron-nickel-cobalt alloy or iron-nickel alloy.

[0037] As shown in Figure 9, the solder layer 5 is made of silver-copper solder paste obtained by mixing silver-copper mixed powder with an organic binder. Existing technology requires manual placement of silver-copper solder sheets on the surface of the ceramic part, followed by placing the metal cover plate 2 on the silver-copper solder sheets before brazing. Since the silver-copper solder sheets are very thin (0.06-0.1mm), they are difficult to handle when placed on the ceramic part 1, leading to issues of omissions or under-placement during manual placement. This can easily result in welding leaks and poor welding due to missing solder sheets or wires after brazing. This invention uses silver-copper paste instead of silver-copper solder sheets and employs screen printing technology to evenly print the silver-copper paste onto the metal cover plate and leads. This not only reduces labor costs but also eliminates omissions and improves processing efficiency.

[0038] Compared with the traditional DIP shell: the pin 3 of the application which needs to improve the current load is heat sink treated, under the premise of having spare space on the side wall of the ceramic piece 1, the internal connecting line is properly widened, and a sufficient number of hollow holes 4 are marked; by filling the tungsten paste connected to the lower layer, and then connected to the side metal pad from the lower layer, a parallel circuit is formed, which reduces the on-resistance and increases the current load, solves the technical requirement of passing through 50VDC, 40A, on-time 100ms, off-time 900ms, and over-load current, so as to well meet the user's high integration, high current load packaging requirements; the on-resistance between the pins 3 after heat sink treatment can be lower than 20mΩ; the aperture of the hollow hole 4 which is not filled with tungsten paste in the heat sink treatment is 0.20-0.50mm, and the height of the filled metal solid hole is 0.25-2.00mm; the ceramic packaging shell provided by the application has one or more cavities, up to 10, which can install multiple chips and various passive components inside, meeting the user's high integration packaging requirements.

[0039] In order to ensure the long-term reliability of the product, the product is tested after molding for many times of matching, the packaging air tightness is high, the air tightness meets ≤1×10-3 Pa·cm3 / s, A4; the reliability is high, can meet the temperature cycle: -65℃~175℃, 200 times, constant acceleration: 30000g, Y1 direction, 1min; each test is qualified, thereby proving that the high reliability of the product meets the industry standard requirements.
