The LED door and the emperor have entered the door of the lighting field, making the brightness of the light become the target of the manufacturers. After all, when the LEDs are assembled into a lighting bulb, the total lumens output is whether the LED lamp can meet the lighting requirements and replace the biggest key of the traditional bulb. However, high-power LED chips can achieve higher lumens in single-crystal packages, but they are far less efficient than low-power LED chips. This also makes the LED downstream packaging factory separate two factions, one is dedicated to the mainstream high-power LED chip packaging factory, the other is the main low-power LED chip for poly-package (multi-chippackage) packaging plant.
The technical application of high-power LED single crystal packaging has matured in the lighting market. These technologies also prove that LED applications are feasible on the illumination, but the LED single crystal package is easy to produce glare and uncomfortable when applied to illumination. The color of the color, technically needs to break through. There are no other better solutions than secondary optics such as reticle or lens. In addition, the high-power single-chip package is quite mature in mass production technology, but a single chip operates under high current (>700mA), and a hot spot with a relatively high heat density will be generated on the chip, which makes the package factory In the way of packaging, it is also necessary to consider the thermal stress on the decarburization and soldering problems.
On the contrary, under the same total power, the low-power chip not only has a higher lumen count, but also because the heat source is dispersed on each chip, it is less likely to generate hot spots. Therefore, purely in terms of light and heat, the low-power polycrystalline package has the upper hand.
Of course, related manufacturers are still constantly working to improve the lumens of LED lighting. Edison Optoelectronics has launched a customized polycrystalline package high-voltage LED products, the main LED bulb market, the best luminous efficiency of the product can reach 120 lumens per watt, the new products have been successfully shipped in the near future. Wu Jianrong, chairman of Edison, said that in addition to focusing on the lighting market, high-voltage LEDs can effectively reduce product costs, which is also the main consideration for future Edison product development.
1.0mm (.039") Female Headers
Overview
Whenever there is a need for fitting small-sized connectors in compact devices, the 1.0mm pitch female header, or sometimes referred to as header connector, is ideally suited for this application. Not only does this female header space-savvy, but it is also designed for vacuum pick and place that makes it suitable for high volume automated manufacturing.Antenk offers these low profile, easy-install, SMT or THM miniature female connector plugs at high quality and affordable China-quoted price, for board-to-board connection, snuggly fitting the pins of a male header and acting as a receptacle.
Assembly and service is simple with either vertical (straight), elevated or at a right angle configuration/orientation, which can dissipate current of about 1.0 A or less in a tape and reel packaging. The filleted corners can also remove shadowing allowing optimization of LED output.
Also, the 1.0mm pitch female headers are 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).
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.
1.0mm vertical single row female header, 1.0mm vertical dual row female header, 1.0mm Elevated single row female header, 1.0mm Elevated dual row female Header, 1.0mm right-angle single row female header and 1.0mm 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.
1.0mm Right-angle Dual Row female header, 1.0mm SMT Single row female header, 1.0mm SMT Dual row female header and 1.0mm Elevated Dual Row female Header are Antenk`s SMT female headers.
Soldering Temperature for 1.0mm 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
1.0mm 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
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 1.0mm 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 1.0mm Pitch Female Headers
Customizable 1.0 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.
