Every product you buy is covered by a warranty. Depending on your country, it's either one year or two years. The best way to use a warranty is to keep it in its original packaging and make sure you have a copy of your sales receipt. When something goes wrong, go through that manufacturer first. If they can't repair or replace it, they will work with you to get it repaired locally in many cases even shipping replacement parts out immediately so that repairs can be made quickly. Regardless of how things shake out though, always keep those receipts and warranties!

Features:
Your product must have durability, so discuss about what material it is made from and why that's important. Materials often used in these products are aluminum alloy case. Aluminum Alloy is a good choice due to its lightweight durability. When discussing durability do not assume customers understand what material it is made from - make sure there is no confusion about what you mean when using material names.

The clockâ??s lens is made of high-quality matt acrylic that works to diffuse light and prevent glare. You donâ??t have to squint your eyes or use sticky notes to block out unwanted lights when you wake up at night. The lens also keeps UV rays out, extending its lifespan and keeping it looking sharp for years to come. Some LED clock buyers note that they need to dim their room lights in order for these clocks to display correctly, but all in all, reviewers feel like these are pretty durable products and a good addition (or replacement) for their kitchen wall or bedroom dresser.

 Inquire Now  
What is Flexible PCB?
Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Immersion Tin PCB are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.
What are Advantages of Flexible Printed Circuit Boards?
Flexible printed circuit boards offer a number of potential benefits including:
Saving Space. Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities.
Maximum Reliability. A flexible printed circuit board requires fewer interconnects, which in turn requires fewer contact crimps, connectors and solder joints. Simply put, a flexible PCB board does not contain as many potential sources for failure, which enhances their reliability.
Enhanced Capabilities. The flexible printed circuits boards are compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals.
Cost Savings. Cost-saving advantages of Flexible PCBs include reduced material and packaging demands, lower parts replacement costs and assembly errors that could result in the need for repairs.
Thsse benefits make flex PCBs ideally fit for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.

What is HDI PCB
High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter.
By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allow designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
HDI PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices.
Advantages of HDI PCB
The most common reason for using HDI technology is a significant increase in packaging density. The space that obtained by finer track structures is available for components. In addition, overall space requirements are reduced will result in smaller board sizes and fewer layers.
Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.

High-TG PCB High Temperature PCB fr4 Material
The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material.
Circuit board material must flame-resistant, it canâ??t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg).
The higher Tg point means higher temperature requirement during lamination. And the Aluminum clad Circuit Boards will be hard and crisp, which will affect hole and the electrical properties.
Ordinary PCB materials at high temperatures, not only will be soften, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply.
General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees.
The higher of Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics.
FR4 is a code name for grade of Epoxy Glass material.
Tg means Glass Transition Temperature.
When the working temperature reaches to the melting point, that means the temperature exceeds the Tg value, the status of pcb material will be changed from glassy to liquid, which will affect the function of pcb. And this value is related to the stability of the pcb dimension.
As usual, made with Tg â?¥ 170â?? pcb material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.
