As global healthcare costs soar and the population ages, the demand for portable medical diagnostic equipment and treatments is growing rapidly in patients' homes and in underserved and remote areas. According to a recent industry report (Home Healthcare Market Current Trends, Opportunities & Global Forecasts to 2016), new devices and markets are booming to meet patients’ home healthcare needs, including respiratory therapy, home infusion therapy, rehabilitation services and monitoring for chronic medical patients. In addition to predicting an average annual growth rate of 7.7% for the home healthcare market through 2016, the report also states:The most important healthcare development trend observed recently is the shift from hospital to home for treatment to gain cost advantages and reduce hospital expenditures. In addition, the shift from treatment to active monitoring has also created new opportunities for the home healthcare market. Patients prefer to receive healthcare at home rather than in hospital due to convenience and high cost-effectiveness.Patient monitors are gradually moving from hospital bedside equipment to home healthcare or connected systems. Micro interconnect I/O solutions and innovation capabilities are in line with the trend of telehealth applications requiring smaller, lighter and integrated solutions.As healthcare providers and patients drive these shifts, leading electronics innovators are addressing the technical challenges of transitioning devices and instruments that have traditionally been used in doctor's offices, clinics, and hospital settings into patients’ homes. Among these challenges, power management plays a major role in patient ease of use, size, performance, and durability for such medical devices. Therefore, it is important for engineers making system-level tradeoffs to make power management decisions early in the design cycle.The power connector industry is gradually introducing new extremely small low-profile high connectors, innovating in the smartphone industry to meet the growing demand for improved portability and miniaturization of medical instruments and equipment. Micro-Electrical Mechanical System (MEMS) is an innovative approach that combines electrical and mechanical components to provide systems with unprecedented tiny sizes, and this approach has become an important technology of choice for small and portable designs in the booming healthcare market.

Combined sales of drones are expected to reach $90 billion over the next decade, with annual sales rising from $8 billion in 2015 to between $12 billion and $14 billion by 2025. The military market will continue to lead the market, with an estimated market share of around 70%. The remaining market share is estimated to be around 25% for the consumer market and 5% for the civilian market.

The power connector generally consists of a plug and a socket, wherein the plug is also called a free-end connector and the socket is also called a fixed connector. The connection and disconnection of the circuit is achieved through plugs, sockets and insertion and extraction, thus various connection methods of plugs and sockets are produced.This is known to many operators. The following is an analysis of the precautions in use:1、Termination 1）When terminating the power connector, the termination and inspection should be carried out strictly in accordance with the corresponding termination specifications or requirements, and the termination should be carried out according to the corresponding contact number.The maximum insulation thickness between the selected cables and wires should match the distance between the contacts, and the cable cores should match the contact terminals. When crossing or paralleling between contacts, the diameter of the twisted multi-strand cores should be considered, and crossing or paralleling between the contact crimping holes is prohibited;

There are many types of electronic connectors, but the manufacturing process is basically the same. Generally speaking, it can be divided into four stages：Stamping，Plating，Molding，Assembly.1、Stamping: The manufacturing process of electronic connectors generally starts with stamping pins. Electronic connectors (pins, terminals) are stamped from thin metal strips using large high-speed stamping machines.One end of a large roll of metal strip is fed into the front end of the stamping machine, and the other end passes through the stamping machine hydraulic workbench and is wound into a take-up wheel, which pulls out the metal strip and rolls it up to stamp out the finished product.2、Plating: After the terminals and pins are stamped, they should be sent to the electroplating section. At this stage, the electronic contact surface of the connector will be plated with various metal coatings.The twisting, breaking or deformation of the pins occurs during the process of sending the stamped pins to the electroplating equipment. Through the detection technology described in this article, such quality defects can be easily detected.However, for most machine vision system suppliers, many quality defects that occur during the electroplating process are still off-limits for inspection systems. Electronic connector manufacturers want inspection systems to detect various inconsistent defects such as small scratches and pinholes on the surface of connector pin plating.Although these defects are easy to identify for other products (such as aluminum can bottoms or other relatively flat surfaces); due to the irregular and angled surface design of most electronic connectors, it is difficult for visual inspection systems to obtain images sufficient to identify these subtle defects.Since some types of pins need to be plated with multiple layers of metal, manufacturers also want the inspection system to be able to distinguish between various metal coatings in order to verify whether they are in place and the correct proportions. This is a very difficult task for a visual system using a black and white camera, because the grayscale images of different metal coatings are actually almost the same.Although the camera of the color vision system can successfully distinguish these different metal coatings, the problem of difficult lighting still exists due to the irregular angles and reflections of the coating surface.
