Full Turnkey Medical Device Manufacturing Key Service Offerings In-house Capabilities  Transfer to Manufacturing The Healthcare & Medical PCB applications we serve KFEMS fabricates and assembles medical PCBs for a wide range of medical devices, such as: Medical imaging devices Medical monitoring systems Robotic surgery Radiation therapy or radiotherapy The testing standards we follow for Medical PCBs We perform constant testing at each step of the manufacturing process to ensure reliability of the medtech circuit boards. Automated optical inspection (AOI): AOI captures images of the PCB with either a single 2D camera or two 3D cameras. The captured image is compared with the schematic. If the board does not match the schematic, the board is sent to manual inspection. Solderability test: Ensures that the solder joints are reliable. Ionic contamination testing: Ionic contamination testing is performed to detect ionic residues resulting from the fabrication and soldering steps. Peel test: Determines the measure of strength required to peel the laminate from the circuit board. Micro-sectioning analysis: The inspection is carried out to determine the quality of the circuit board and also to spot internal failures. Flying probe test: Test probes move from test points to other test points and check for opens, shorts, other issues. Time-domain reflectometer (TDR): TDR impedance measurements are essential for ensuring signal integrity. It also checks for electrical discontinuities in connectors, or any other electrical path. How we meet your high-reliability requirements with full traceability Under IPC-6012 class 2 and class 3, we build standard, advanced, and micro boards with high accuracy. Our advanced boards come with UL 94 V-0 flammability standards.

News outlets have reported on breakdowns with overseas shipments of vital medical equipment due to shelter-in-place policies, as well as geo-political delays that seem unlikely to resolve quickly. Quality also seems to be an issue, since China has implemented more export inspections:     All these factors will motivate the U.S. medical equipment industry to relocate some of its manufacturing back to the United States. This will lead to opportunities fabricating and coating the parts needed to make respirators/ventilators, N95 masks, other PPE supplies, hospital beds, etc. An uptick in this part of the manufacturing and finishing market is already underway.      One of the preferred coatings for steel or aluminum medical equipment is powder coating. This is due to its superior hardness/durability and chemical resistance. The chemical resistance of polyester powder makes it one of the most easily sanitized painted surfaces. Polyester powder coating is resistant to all the CDC-recommended sanitization chemicals, such as distilled water, bleach, hydrogen peroxide, ammonia, alcohol, phenolics, steam, and UV light, per the BIMFA clean guide:       Some hospitals and laboratories are specifying anti-microbial coatings. These coatings contain a small amount of silver that is safe for human contact but inhibits the growth of microbes. This requires a specialty powder that is applied just like any other polyester powder. It also has been used for children’s playground equipment and food processing equipment. Powder manufacturers such as PPG have product lines for these applications:      There are immediate and future opportunities for fabricators and coating shops. Large medical equipment manufacturers will be setting up new operations in the U.S. They are going to need fabricated carts, frames, furniture, electronics housings, and durable parts that meet the needs of healthcare facilities in the United States. Other industries might migrate to more durable finishes as well, due to the sanitization-friendly nature of powder coatings.     We provide Precision Medical Equipment Circuit Board PCBA RoHS PCB Board Assembly services. KFEMS is your one stop turnkey PCB assembly factory. Looking forward to your inquiry.

The core board is an electronic motherboard that packages and encapsulates the core functions of the MINI PC. Most of the core boards integrate CPU, storage devices and pins, which are connected with the supporting baseboard through the pins to realize a system chip in a certain field. People often refer to such a system as a single-chip microcomputer, or an embedded development platform. Because the core board integrates the common functions of the core, it has the versatility that one core board can customize various bottom boards, which greatly improves the development efficiency of the single-chip microcomputer. Because the core board is separated as an independent module, it also reduces the difficulty of development and increases the stability and maintainability of the system. Core motherboard PCBA control board is one of the very important cores of electronic products.     Components:     CPU The CPU is the most important part of the core board and consists of a computing unit and a controller. If a computer is compared to a person, then the CPU is his heart, and its important role can be seen from this. No matter what kind of CPU, its internal structure can be divided into three parts: control unit, logic unit and storage unit. These three parts cooperate with each other to analyze, judge, calculate and control the coordination of various parts of the computer.      Memory The memory is a component used to store programs and data. For a computer, only with memory can it have a memory function and ensure normal operation. There are many types of memory, which can be divided into main memory and auxiliary memory according to their use. The main memory is also called internal memory (referred to as memory), and the auxiliary memory is also called external memory (abbreviated as external memory). External storage is usually magnetic media or optical discs, such as hard disks, floppy disks, tapes, CDs, etc., which can store information for a long time and do not rely on electricity to store information, but driven by mechanical components, the speed is much slower than that of the CPU. Memory refers to the storage component on the motherboard, which is the component that the CPU directly communicates with and uses to store data, and stores the data and programs currently in use (that is, in execution). Its physical essence is one or more groups with An integrated circuit with data input and output and data storage functions. The memory is only used to temporarily store programs and data. Once the power is turned off or a power failure occurs, the programs and data in it will be lost. Platform type The core board is divided by platform type, mainly by CPU chip type. The popular mainstream platforms are ARM, Samsung, and INTEL. And KFEMS Technology Co., Ltd. can support PCBA assembly produce core motherboard PCBA control boards with excellent performance.      ARM platform      The three major characteristics of the ARM processor are: low power consumption, strong function, 16-bit/32-bit dual instruction set and many partners. Small size, low power consumption, low cost, high performance; support Thumb (16-bit)/ARM (32-bit) dual instruction set, and can be well compatible with 8-bit/16-bit devices; a large number of registers are used, and the instruction execution speed is faster ;Most data operations are completed in registers; the addressing mode is flexible and simple, and the execution efficiency is high; the instruction length is fixed. See Mattel’s Armboard series products have played these advantages of the ARM platform very well.      Samsung platform The representative chip on the Samsung platform is S5PV210, also known as “Hummingbird”, which is an application processor for smartphones and tablet computers and other multimedia devices launched by Samsung. S5PV210 uses ARM CortexTM-A8 core, ARM V7 instruction set, main frequency Up to 1GHZ, 64/32-bit internal bus structure, 32/32KB data/instruction level-1 cache, 512KB level-2 cache, can achieve 2000DMIPS (200 million instruction sets per second) high-performance computing capability.       INTEL platform       The INTEL platform refers to the X86 architecture platform, and the x86 architecture is CISC (Complex Instruction Set Computer, Complex Instruction Set Computer) with variable instruction length. The memory access of word (word, 4 bytes) length allows non-aligned memory addresses, and the word is stored in the memory in the order of low-order byte first. Forward compatibility has always been a driving force behind the development of the x86 architecture (design needs dictated this factor and often led to criticism, especially from rival processor advocates and theorists, for a widely considered bewildered by the continued success of backward-designed architectures). However, in newer microarchitectures, x86 processors convert x86 instructions into more RISC-like microinstructions before executing them, thereby obtaining superscalar performance comparable to RISC, while still maintaining forward compatibility.

Through the 4G module, we can realize the transmission of industrial equipment data to the remote control center through the wireless 4G network, and from The control center remotely communicates data with industrial equipment through the 4G module. In this way, the centralized management and centralized monitoring of industrial equipment through the wireless 4G network can be realized. Through the 4G module, the operating labor cost can be greatly reduced In recent years, the Internet of Things industry has developed rapidly, and various Internet of Things modules have been used to replace manpower and have been applied to all walks of life. So what is the working principle of the 4G module? Let’s analyze how the 4G module works. The 4G module communicates based on the 4G network, and the 4G module refers to the general term for supporting LTE network standards such as TD-LTE and FDD-LTE. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. KFEMS integrates the radio frequency and baseband of the 4G module on a small PCB board to complete the functions of wireless reception, transmission and baseband signal processing. The software transmits the modbus data of the lower computer to the server through the 4GLTE network, and supports heartbeat packet and registration packet functions. And it can support software to support functions such as voice dialing, SMS sending and receiving, and dial-up networking. Features of 4GDTU module The 4GDTU module TAS-LTE-363 has 4G full Netcom function, adopts high-gain antenna, 4G communication module SMT assembly provided by Xinjingfu, stable signal reception and transmission, and stable communication. 1.
