Human health and longevity are inseparable from medical treatment. One of the reasons for the development of medical technology is the development of medical machinery. And the development of medical machinery is inseparable from the use of pick and place machine. The occurrence of SMT medical devices makes sure the production of PCB in medical terms. No matter household thermometers, medical ventilators, body temperature measuring instruments, etc., SMT machines are needed.

PCB Enclosure Design Guidelines

·Ensure MCAD and ECAD tools use the same data format.

·Select the right component package for the PCB enclosure.

·Ensure that the PCB enclosure box fits the board size.

·Ensure board cutouts are accurately aligned with component placement.

·Understand the environmental hazards of the installation.

·Consider the impact on signal transmission.

·Select PCB enclosure materials that meet thermal requirements.

·Consider equipment tolerances.

 

What is a PCB Enclosure

PCB enclosure is equipment to store and protect printed circuit boards, which can offer a PCB cover. In order to protect the PCB from environmental factors, adding possible consideration of electromagnetic compatibility (EMC), it is almost certain that the PCB will be placed in some form of enclosure. Inevitably, the PCB enclosure will interfere with the free flow of air around the PCB and therefore also have an impact on the thermal performance of the system

 

What is a PCB Enclosure

Safety Distance Between PCB and PCB Enclosure

The production and processing of PCBA for the board and the PCB enclosure will generally have safety distance requirements. This distance can ensure that our PCBA board will not be damaged in some harsh environment.

 

The safety distance between the PCBA board and mounting PCB in the enclosure includes electrical clearance (space distance), creepage distance (distance along the surface), and insulation penetration distance.

 

I. PCBA board and the PCB enclosure of the electrical clearance requirements: electrical clearance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by air. According to the measured working voltage and insulation level, the distance can be decided.

 

II. PCBA board and PCB enclosure creepage distance requirements: creepage distance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by the absolute insulation surface.

 

III. PCBA board and PCB enclosure insulation penetration distance requirements: it should be in accordance with the working voltage and insulation application occasions in line with the following provisions.

 

1. For working voltage not exceeding 50V (71V AC peak or DC value), there is no thickness requirement.

 

2. The minimum thickness of additional insulation should be 0.4mm.

 

3. When the reinforced insulation is not subject to any mechanical stress at the normal temperature that may lead to deformation or performance degradation of the insulation material, the minimum thickness of the reinforced insulation should be 0.4mm.

 

HX will custom PCB enclosure with a safety distance for your use!

Application of Electronics PCBA

 

Electronic PCBA is mainly used in computer motherboard mouse board, graphics cards, office equipment, printers, copiers, shakers, all kinds of chargers, calculators, digital cameras, radios, TV motherboards, limited TV amplifiers, cell phones, washing machines, electronic scales, telephones, LED lamps, etc., and in the application of home appliances: air conditioners, refrigerators, stereos, MP3; used in industrial equipment In industrial equipment: GPS, automobile, instrumentation, medical instruments, aircraft, military weapons, missiles, satellites, etc.

 

Process of Manufacturing Power PCBA

 

The manufacturing of the power PCBA board is divided into two parts. One part is the manufacturing of the PCB itself. The other part is the soldering of the components. Only after soldering components, the power PCBA can achieve its function and value. The process of welding components on the PCB, called PCBA, namely printed circuit board assembly, which is the empty PCB after SMT, and then after the entire process of DIP plug-in.

FR4 PCB

FR4 is the most important material in the PCB assembly. Electric engineers and technicians normally design PCB boards with the FR4 PCB. There is a big demand for FR4. FR4 printed circuit board is normal and easy to design. The FR4 PCBs are popular as they are cost effective and can be widely used.

High-TG PCB

Normally FR4 Tg is 130-140°, moderate Tg is over 150-160 °, High-Tg is greater than 170°.The higher of Tg, the better performance of PCB moisture resistance, heat resistance, chemical resistance, stability and other characteristics.

What is PCB?

PCB is the abbreviation of the printed circuit board. PCB composed by insulated baseboard, pads for electronic components and copper foil connecting wires. PCB can replace complex wiring to achieve circuit connection between components in the circuit.

 

PCB is the motherboard of electronic components. Before the advent of PCB, the interconnection between electronic components was done directly by wires. Today, PCB has been widely used in the electronics industry, due to the PCB tecnology, manual wiring errors can be avoided, and electronic components can be automatically DIP or SMT, automatic soldering, and automatic detection, ensuring the quality of electronic device and improving labor productivity, reduce costs as well.

 

What Is the Difference Between PCB And PCBA?

PCB is a blank circuit board without any electronic components soldered on. It just composed by baseboard with pads and copper foil connection wires.

 

PCBA is a complete assembled board with electronic components. We apply surface mount technology and through-hole soldering technology solder the components onto the board. The components are soldered to the board can be SMD, through hole, UBGA, QFN, POP, leadless chips, connectors and terminals.
