Problems solved by technology

However, it is necessary to make conductive adhesive solder balls, and there are also requirements for flip-chip soldering equipment, which is difficult to operate and high in cost.
The method of direct soldering and welding leads has the lowest cost, but the uniformity and stability between solder joints are poor, the yield is low, the precision is low, and the connection of high-density microstructure cannot be realized, and the temperature is high during the welding process, which is easy to cause flexibility. device curl

Embodiment 1

[0028] In this implementation example, the flexible neural microelectrode is taken as an example, and the flexible connector described specifically will realize the interconnection between the flexible device (flexible neural microelectrode) and the device. According to the size of the welding site of the flexible microelectrode (the welding site is a 4×4 lattice, and the size of each site is 400×400 microns). The corresponding flexible connectors are made by MEMS micromachining technology. The connection end of the flexible device and the device is designed as a flat flexible cable interface, which can be directly connected to the flexible cable connector of the device and is easy to replace. The connection end with the flexible device is designed as a through-hole structure, such as figure 1 shown.

[0029] 1. Align the correspondingly manufactured flexible connector 1 with the flexible device 2, such as figure 1 As shown, a flexible connection device with a through-hole ...

Embodiment 2

[0036] This implementation example specifically describes the process in which the flexible connector connects the flexible device to the flexible device. The corresponding flexible connectors are made by MEMS micromachining technology. Both ends of the flexible connector are designed as through-hole structures, which are connected with two flexible devices, such as Figure 5 shown.

[0037] 1. Align the correspondingly fabricated flexible connector with the flexible device, such as Figure 5 As shown, a flexible device with a through-hole structure is placed over the flexible device to align the soldering sites.

[0038] 2. Use a small amount of adhesive or glue to attach the flexible device to the flexible connector, such as Figure 6 As shown, it is ensured that the welding position of the flexible device and the flexible connector will not be dislocated during the subsequent operation.

[0039] 3. Drip heat-curable conductive adhesive at each corresponding welding poin...

Abstract

The invention relates to an interconnecting method for a flexible device and a used flexible connector. The interconnecting method for the flexible device is characterized by comprising the following steps: a) manufacturing the flexible connector with a through hole characteristic welding locus according to the size of the flexible device; b) aligning and fitting the through hole characteristic welding locus of the flexible connector and a welding locus of the flexible device to be connected, and coating conductive adhesive at the welding loci to realize connection and communication; and c) coating or depositing a polymer at the welding loci to insulate and encapsulate a connected part. The flexible connector is an elongated membrane, and has a three-layer structure of polymer, metal and polymer; two ends of the flexible connector are the welding loci or connecting loci exposed by the metal layer; and the middle of the flexible connector is an embedded metal connecting line. The provided microelectrode connector based on a flexible polymer material has the characteristics of compatibility with the prior micro-electromechanical processing technology and standardized mass manufacture. The flexible connector ensures the effective connection and signal transmission between the flexible device and an equipment or between the flexible devices, and solves the problem of connection reliability of the flexible device.

Description

technical field [0001] The invention relates to an interconnection method of flexible devices and a used flexible connector. Background technique [0002] With the development of flexible micro-patterning technology in microfabrication technology, the research and application of flexible devices has developed rapidly. Because flexible devices have many advantages such as bendable, foldable, even wearable, not easily damaged, light in weight, and small in size, the development and application of flexible devices has become a hot spot in international research. It has been applied in many fields such as biomedicine, aerospace, sensors and organic electroluminescent display devices (OLED). Flexible devices need to be connected with necessary devices to realize their functions. But there are still some deficiencies in several connection methods at present. [0003] The MFI technology (Microflex Interconnection Technology) developed by Stieglitz et al. realizes the flexible co...
