Seminar site
In order to better promote the technological progress of the washing machine industry, protect the rights and interests of consumers, and let more consumers understand the advanced nature and importance of the new national standard of washing machines, the Institute of Testing and Measurement Technology of China Household Electrical Appliances Research Institute and the magazine of Home Appliances Technology On April 16th, the “Technical Seminar on the Advancedness of GB/T 4288-2018 Standard and Its Social Value†was held. This seminar is the first time to interpret and discuss the standards after the release of the new national standard for washing machines. From the perspective of national standardization construction, testing methods and industry development, the conference introduces the significance and social value of the new national standard revision of washing machines.
Interpretation of "new standard"
Compared with the 08 version of the standard, the new standard proposes "washing performance", "rinsing performance", "wear performance", "wash barrel (cylinder) effective volume", "standby / shutdown power" based on the clear scope of application. Key indicators such as “vibration performanceâ€, among which the first three are core indicators, which can reflect the quality of the entire washing machine.
The concept of “effective volume of washing machine washing tub (barrel)†introduced by the new standard is changed from the original rated load (kg) to the rated inner barrel (barrel) volume (L) of the washing machine, eliminating the capacity of the virtual standard and allowing the inside of the washing machine. The size of the barrel (barrel) has become more intuitive, allowing consumers to see at a glance. For rinsing performance and wear performance indicators, the new standard introduces a percentage labeling method that allows consumers to easily understand the washing ability of the washing machine.
GB/T 4288-2018 main performance indicators
In addition to the standardization of the “core indicators†test and evaluation methods, the new standards also consider adjusting relevant technical indicators, such as power consumption, water consumption, shutdown/standby power, annual power consumption, vibration and other indicators. On this basis, clearly label the content and labeling methods to ensure the disclosure and symmetry of the product's various consumption information.
In addition, the new standard also combines the main performance indicators of the washing machine, and makes a quantitative assessment of “gradingâ€. The highest level is “A+ level†(international leading level), which means that it has reached or exceeded the international advanced level, and removed the original “D†grade products, and correspondingly added “rinsing performance†and “wear performance†and Grade indicator of "vibration performance".

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).

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
