PCB Quality

When your PCBs are manufactured, it is essential to you--- the end user--- that they are made to your exact specifications. At EPCB, our quality assurance program is multifaceted. We always make several samples, only they are perfectly tested, can we fabricate your order in a large volume. And this means you are ensured of getting the highest quality PCBs that are made right the first time. Besides, if you do not assign a particular requirement, IPC Class 2 will be the default. Each board also undergoes a full inspection consisting of a random sampling to determine that the holes and dimensions for each part number are within tolerance. 

Tips for Cleaning Dust

If you notice that your circuit board is collecting dust or grime that keeps it from functioning normally, you may decide to clean the board when you take into consideration the money and time you will spend on purchasing a new one.

There are different methods for cleaning printed circuit boards depending on the type of PCB you have and what dirt or buildup exists. Before you begin to clean your PCB, be aware that any time you do so you run the risk of causing damage to the board and components. Therefore, if the board works normally but is just a bit dusty you must decide if attempting to clean the PCB is worth the risk. For PCBs with only light dust, use an old dry toothbrush, dry paintbrush or the upholstery brush from your vacuum to loosen the dust. Then you can use a can of compressed air to blow the remainder of dust off of the board.

The cleaning process becomes a bit trickier if you have grime on your printed circuit boards. Grime is common with monitor chassis boards that deal with higher temperatures and melting wax from components. Be sure to remove any socketed components before applying detergent and scrubbing mildly to loosen whatever is caked onto your PCB. Since this method may not work 100 percent of the time, it is a good idea to consult a PCB expert to see what you can potentially do to clean your circuit board and get it back into working order. If it cannot be fixed, you will need to place an order for a new board.

UL Certification

UL LLC is an American worldwide safety consulting and certification company headquartered in Northbrook, Illinois. UL provides safety-related certification, validation, testing, inspection, auditing, advising and training services to a wide range of clients, including manufacturers, retailers, policymakers, regulators, service companies, and consumers. Besides, it is one of several companies approved to perform safety testing by the US federal agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories.

EPCB holds a certificate for this standard and prides itself on producing a printed circuit board that is up to the highest expectations of customers. Whether you need to order printed circuit boards for a hobby project or a large-scale application, you can be sure that the experts at EPCB will be able to deliver just what you need. 

PCB Manufacturer

When you are getting ready to place an order for your circuit boards, there are many factors to take into consideration. First of all, you want to be able to work with a manufacturer that has a proven track record of providing customers with PCBs consistently meet and exceed expectations. Also, it is important to order from a printed circuit board manufacturer that demonstrates a commitment to the industry and strives to meet the highest standards for design, quality and efficiency. EPCB holds multiple certifications at each of its divisions in order to ensure that customers are able to get PCBs that will work exactly as needed every time. 

Custom Printed Circuit Boards

One of the most common items that you will find if you take apart the electronics in your home is the circuit board. Printed circuit boards, or PCBs, are the brains of your devices and are responsible for ensuring that it functions as designed. In order to make sure that your product is going to run as you need it to, you will want to design a PCB from scratch. This is due to the fact that you have the ability to layout the board so it can work with the components you need. In addition, by designing a custom board you can be sure that it will fit into the device that you are creating. Hobbyists and large-scale companies benefit from custom PCBs because it gives you ownership over every step of the production process.Our EPCB respects every designer's work, and provides customized service to you. 

Interesting PCB Facts

Have you ever wondered why the solder mask on your printed circuit boards is green? There have been numerous myths and explanations put forward over the years to explain why PCBs are green. We EPCB regard that original masks for PCB were yellow and brown in color but workers easily felt fatigued when they checked circuits on boards for a long time. However, green color could relieve eye tiredness to some extent, so PCB designers decided to use the standard green. Early gramophones and tube style radios used PCBs as far back as the 1920s, but the PCB as we know it today saw first widespread use after World War II.

PCB Board

A printed circuit board, or PCB Board, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have been manufactured into the actual substrate of the board, it is more correctly referred to as printed wiring board (PWB) or etched wiring board. Use of the term PWB or printed wiring board although more accurate and distinct from what would be known as a true printed circuit board, has generally fallen by the wayside for many people as the distinction between circuit and wiring has become blurred. 

Recycle Old PCBs

As we all know, environment pollution is severely serious which does harm to people’s health. So we should do our part to protect the environment as both an individual and a part of our company which will allow us all to conserve valuable resources, reduce energy consumption and create a cleaner environment for our future. We can achieve our objectives by recycling old printed circuit boards which are made from chemicals and materials that are hazardous to the environment. Those raw materials are illegal to dump without special treatment, because if these items make their way into a landfill they will just sit there, allowing the chemicals to potentially seep into the soil or get into water supplies. That’s the reason why we appeal to PCB users and manufacturers to recycle old PCBs. We have the responsibility to ensure that the raw materials are properly disposed of and meet regulations in order to protect our environment.
