As a pioneer of MEMS, the crystal oscillator market has shown steady development in today's rapidly developing market. “On the analysis of MEMS products currently on the market, Yole Développement made the MEMS crystal oscillator market the most promising market in 2015, and it is the highest CAGR market for 2009 to 2015. It is expected that the MEMS crystal oscillator will From USD 7.9 million in 2009 to USD 644.9 million in 2015,†said Vice President of VTI Consumer Electronics. Sten Stockmann said that VTI crystal products will use VTI's 3D MEMS and packaging technology. VTI currently uses Chip-on-MEMS technology to package cost-rate sensors. The same technology will be applied to the crystal, but the opposite MEMS-on-Chip technology.
Mature MEMS technology
Quartz Crystals - Most of the high-performance electronic systems are clocked by quartz oscillators - and they face challenges in developing fast consumer devices. The stability and frequency sensitivity of the oscillations, like the size reduction of the quartz oscillator, are mutually constrained because of the increased crystal impedance of these newer oscillators. Small quartz oscillators are more sensitive to vibrations in terms of frequency deviations, just as small packaged oscillators have greater tolerances for mechanical vibrations.
Silicon MEMS oscillators replace quartz crystals. Silicon MEMS oscillators are small in size, low in price, and are less susceptible to shock and vibration.
VTI offers low cost, small size and ultra high performance solutions
MEMS oscillation technology has been popularized in the market, and it faces the problems of low accuracy and large temperature drift. A typical MEMS oscillator can have a frequency of 10,000 ppm. In addition, the MEMS oscillator temperature drifts around 30ppm/degrees Celsius.
With this oscillation technique, the ASIC must be designed to compensate for frequency errors, increasing size, cost, power consumption, and noise. The result is an increase in the cost of the oscillator and no competitive advantage.
VTI technology serves these common obstacles and provides a competitive quartz crystal. In early 2011, VTI will release its first crystal.
1.27mm (0.05") Pitch Pin Headers
Antenk offers a variety of high quality and competitively priced 1.27mm pitch single,dual, three and quad row pin (male) headers used in many board-to-board PCB connections, fitting small-sized, densely-packed devices.
This low-profile component is made from high-temperature thermoplastic and is offered with several means of connections and mounting styles such as through-hole (THM) or surface mount (SMT) and can be in vertical (straight), elevated or at a right angle configuration/orientation dissipating current of about 1.0 A or less.
The pin (male) header is generally mated with receptacle or stackable header connectors (female sockets). This types of pin headers are suitable for PCB board to board connection or for signal transmission application.
Applications of 1.27mm Pitch Pin Headers
Small equipment and devices can highly benefit from the small but robust stature of the 1.27mm pitch pin header as its material is tested for high-vibration and shock requirements of the automotive, industrial, and consumer electronics industries. This 1.27mm pitch pin header is widely used in diverse applications such as:
Medical Diagnostic and Monitoring equipment
Communications: Telecoms and Datacoms
Industrial and Automotive Control and Test
Retail and Point-Of-Sale equipment
Mil/Aero and Home Security
Solar applications
Weighing systems
Vehicle infotainment
Computer peripherals
Telecommunications
Heart monitors
Mount Type:
Through-hole vs Surface Mount
1.27mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin 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.
1.27mm vertical single row header, 1.27mm vertical dual row header, 1.27mm Elevated single row pin header, 1.27mm Elevated dual row pin Header, 1.27mm Right-angle single row header and 1.27mm Right-angle dual row 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.
1.27mm Right-angle Dual Row pin header, 1.27mm SMT Single row pin header, 1.27mm SMT Dual row pin header and 1.27mm Elevated Dual Row Pin Header are Antenk`s SMT pin headers.
Soldering Temperature for 1.27mm Pitch Pin Headers
Soldering SMT pin connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.
Pin-Type:
Vertical (Straight) and Right-Angle
1.27mm pitch headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle male header.
Vertical or Straight Pin (Male) 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 Pin (Male) 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
Elevated Pin Header Orientation
Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
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.
Single, Dual or Multiple Number of Rows
For a 1.27mm straight or vertical male pin header, the standard number of rows that Scondar 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 2-50 pins while for dual row, the number contacts may vary from 4-100 pins.
Pin Material
The pins of the connector have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Breakaway design
The pin headers are also equipped with a breakaway design making them fully compatible with their female receptacles.
Custom 1.27mm Pitch Pin Headers
Customizable 1.27 mm pitch pin 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 numbers 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.
Antenk also offers a range of custom Tape and reel carrier strip packaging cavities.
