The rapid development of the world's emerging industries has brought about the dilemma of standard revision and revision, and the LED lighting industry is no exception. Guangdong is one of the important LED industry bases in China. It has been in the forefront of the country in promoting the popularization and application of LED lighting. Since the beginning of 2009, it has launched the “Ten Thousand Miles†high-power LED street lamp industrialization demonstration and promotion project, breaking through the industrial development. Significant results have been achieved in terms of technology, funding and market bottlenecks. This year, the Guangdong Science and Technology Department has set up a major technology special plan for “Guangdong Province Green Lighting Demonstration Cityâ€. When large-scale promotion of LED street lamps, it has encountered many steps in the standard revision process, from drafting to release. The indicators even face the situation that the standard is outdated, which makes the user's lack of scientific evaluation of the quality of LED street lights directly affect the progress of the promotion.
To this end, led by the Guangdong Province Semiconductor Lighting Engineering Provincial Federation of Industry, Education and Research Innovation Alliance, the Foshan Research Institute of Sun Yat-sen University, Guangdong Provincial Institute of Standardization, Guangdong Province Technology and Economic Research and Development Center, Guangdong Province Product Quality Supervision and Inspection Center, organized and implemented Guangdong Province Green Lighting Demonstration City Product Benchmarking Index Research and Implementation†Major project. The core of the project is in the field of LED lighting industry. In view of the insufficient development of LED lighting emerging industry technology and rapid technological advancement, we select product indicators that are considered to have “significant relationship†with the quality of LED lighting products, and pass benchmarking index. Relatively determine the quality of the product, thus establishing an innovative dynamic LED lighting product quality evaluation system, combined with third-party testing and unified platform evaluation, the quality and energy efficiency of the current LED lighting products on the market (first from the street lights) Evaluation and positioning grading. The testing methods and standards will be dynamically updated according to the latest published standards and technical methods at home and abroad.
This method will help to abandon the dispute and solve the common problems encountered in the current LED lighting product quality supervision, testing technology development and platform integration. Breaking through the current imperfect standards in the development of LED lighting industry, the detection methods can not keep up with the bottleneck of technological development. Establish a dynamically updated product benchmarking index and product standard testing and certification system to make breakthroughs in public technology such as standards, certification and testing of LED lighting products, and provide a scientific quality assessment system for selecting products in Guangdong green lighting demonstration cities.
The implementation of the project will also facilitate the continuous analysis and research on the technical development level and market application status of LED lighting products, clarify the technical trends and support priorities of the industry, guide the direction of industrial R&D, and provide science for the technical roadmap of LED lighting industry. The basis can be used to locate the current stage of industrial technology development, but also to form an alliance technical standard, and even provide a sufficient and scientific basis for the industry and national standards, which is extremely important for improving the rationality of industrial layout and promoting the sustainable and balanced development of the industry. The meaning. Provide product quality assessment system for the “Guangdong Province Green Lighting Demonstration City†special plan.
The Science and Technology Department will issue relevant documents and require all the technologies and products of enterprises, universities and scientific research institutions that voluntarily participate in the “Ten Thousand Miles†high-power LED street lamp industrialization demonstration and promotion project and the green lighting demonstration city major special plan inside and outside the province must first pass The LED lighting product evaluation benchmark system is certified. The Science and Technology Department will provide special funds for the relevant departments of cities and regions selected for major special projects, use the benchmark system to conduct regular inspections on products, and the technical level of products, engineering application cost performance and return on investment. Systematic evaluation.
Through the benchmarking index and benchmarking method, the application of the system in the LED lighting industry will also explore new paths and create new experiences for common problems that may be encountered in the standards construction, quality assessment, testing and certification of strategic emerging industries in Guangdong Province. To provide important scientific and technological support for creating a market atmosphere of competitive order, safeguarding and supervision.
2.0mm (0.079") Pitch Female Headers
Overview
2.00 mm pitch female sockets/headers are low-profile connectors designed for signal and low power PC board connections when space is at a premium. Options include through-hole, surface mount and can be customized for mixed technology, press-fit and pass-through terminations. The pins and blades are available in various sizes, counts, amperages, and plating.
The 2.0mm pitch female headers are commonly found in PC`s and are also made to work in Arduino boards, Arduino Pro and Arduino Mega with either single or double-row female headers, facilitating connections for programming and incorporation into other circuits. They have the perfect height for clearing the USB-B connector and great for stacking multiple shields.
Female header always called as [Header connector", Antenk provide widely range of header connector, from 2.54mm (.100″ inch) pitch to 1.0mm (.039″ inch) pitch. The number of pins (contacts) is from 2 to 40 pins per orw. There are three type: Straight (Dip Vertical), Right angle, SMT (surface mount).

Mount Type: Through-hole vs Surface Mount
At one side of this female header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).
Through-Hole (Poke-In)
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.0mm vertical single row female header, 2.0mm vertical dual row female header, 2.0mm right-angle single row female header and 2.0mm right-angle dual row female header are some examples of Antenk products with through-hole mount type.
Surface-Mount
The most common electronic hardware requirements are SMT.
Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
Cost of processing and handling is reduced.
SMT components can be mounted on both side of the board.
Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
2.0mm Right-angle Dual Row female header, 2.0mm SMT Single row female header and 2.0mm SMT Dual row female header are Antenk`s SMT female headers.
Soldering Temperature for 2.0mm Pitch Female Headers
Soldering SMT female connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.
Orientation/Pin-Type: Vertical (Straight) and Right-Angle
2.0mm pitch female headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle female header.
Vertical or Straight Female Header Orientation
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Female Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.
PCB Connector Stacking
For 2.0mm pitch female headers, the orientation is either offered as vertical or right-angle, which are options. Elevated sockets/female headers can be available upon request.
Profile Above PCB
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Elevated Sockets/Female Headers
Elevated Sockets aka Stacked sockets/receptacles or Mezzanine are simply stacked female headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
Choosing this type of stacking configuration promotes the following benefits:
Connector Isolation - the contacts are shrouded preventing cable connection mishaps and good guidance for the mating header connectors.
For off-the-shelf wireless PCB module, stacking height is optimized with elevated sockets.
Offers superior strength and rigidity.
Polarisation prevents users from inverted insertion.
Single, Dual or Multiple Number of Rows
For a 2.0mm straight or vertical female header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.
Pin Material
The pins of the connector attached to the board have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Custom 2.0mm Pitch Female Headers
Customizable 2.0 mm pitch female headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.
Tape and Reel Packaging for SMT Components
Antenk's SMT headers are offered with customizable mating pin lengths, in which each series has multiple number of of circuits, summing up to a thousand individual part number combinations per connector series.
The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation.
