PCB Certifications

Whatever industry you are in, the related certification is an important evidence which can ensure that the goods or service you provided are met the quality standards to some extent. That’s the reason why companies who earn certification for products or services always can build a fine and positive reputation in their industry, and easily keep the loyal customers.

As to printed circuit boards, certifications also plays an important role in assuring  customers of qualified PCBs. There are various certifications for PCB manufacturers and they are involved in every step of manufacturing and assembly. We EPCB firmly comply with the requirements of RoHS compliant and IPC-A-600H-2010 in PCB manufacturing process, and always provide quality certification to our clients. Besides, our engineers always work closely with our suppliers to minimize risk and the potential for loss from defective boards, and that's why we EPCB have a good reputation in the PCB industry.

PCB Panelization

PCB panelization, also known as the processing of boards in an array format, keeps small boards attached to each other within a single, larger substrate. As circuit boards become smaller, changes to production processes must be made in order to ensure that quality is not sacrificed. Panelization helps to address these issues to process multiple small boards through assembly, and is becoming more prevalent as board sizes shrink.

There are two primary reasons for using an array scheme: One is to increase throughput, and the other to allow the manufacturing process to maintain its standard panel size. Besides, smaller boards run the risk of being removed during routing due to the router’s vacuum pressure, while the risk can be largely reduced when boards are arrayed in a good order.

Protecting Printed Circuit Boards from Surges

To maintain the standards you set for quality and performance, it is important to ensure that the components on your PCBs are protected from the elements. Most protection on PCBs is used to guard against the elements such as high temperatures and humidity. However, at times electromagnetic interference and other forces can generate transients that can destroy components. There are different types of surges that can occur, which is why it is important to understand how to best protect your PCBs during the design phase.

Electrostatic Discharge – Also known as ESD, electrostatic discharge is the most common surge. It is caused by a buildup of charge on the equipment or people near it and can produce a surge that damages or destroys semiconductor components.

Electrical Fast Transient – EFT bursts happen when an inductive load is opened. Inductors store energy and when the circuit is opened the energy is released, which can also have damaging effects.

Expect the above two types of pulses, electromagnetic interference, lightning and other forces all can disrupt electronics. Developing PCB designs that protect against these surges help engineers maintain circuit integrity and efficiency in the application.

Tips for Easy PCB Assembly

Tips for Easy PCB Assembly

When you are in the process of designing your printed circuit boards for fabrication, we know that it is important to maximize the efficiency of your PCB in order to reduce your overall cost. In order to do this, the team at EPCB has put together tips to help you along the way. Be sure to start by placing the components that require a specific location on your PCB first. Also, do your best to minimize trace lengths during the design process so you can maximize functionality. 

Submit Gerber Files to EPCB to Help Expedite Your Order

When you submit your files to EPCB, we will check the specification you filled out before placing your order. Then we will evaluate your PCB design, if anything wrong, we will inform you about that and give our suggestion to you. Once these issues are resolved, your PCBs will be made on site and tested by expert engineers for quality assurance before shipping. To learn more about the design and fabrication process, contact a representative at EPCB today. 

Flex Circuits Mistakes

When making your printed circuit boards you want to be able to get the functionality you need to keep your system running and you also want everything to be easy to assemble. There are some common mistakes made with flex circuits, however, that can inhibit your progress. EPCB can help avoid such issues as placing vias outside the stiffener area, which can cause via cracking. Not providing the proper stiffener information can also lead you to getting the wrong product. You also run into problems with flex circuits when placing the edge of the feature closer than to the edge of the board.

Flexible Printed Circuits

Flexible printed circuits were originally designed as a replacement for traditional wire harnesses. From early applications during World War II to the present, growth and proliferation for flex circuits and flexible printed circuit boards continues exponentially. There are many benefits of Flexible Printed Circuits including: assembly error reduction, decreased assembly time and costs, flexibility during installation, high density applications, etc.

Here we want to talk something about design freedom– unlike rigid boards, flex circuits are not restricted to two dimensions. Because they are as flexible as wires or ribbon cables, flex circuit design options are endless. Flex circuits can be designed to meet highly complex and unimaginable configurations while being able to operate in the most hostile environments. Flex circuit designs could entail any of the following:

Highly complex configurations

Withstand hostile operating environments

Single- Double- combinations

Complex interconnections

Shielding

Rigid/flex capabilities

Surface mounted devices

Wiring Tips for Your Multi-Layer Printed Circuit Board

When you are designing multi-layer boards for your product, it is crucial to have a design that allows for maximum efficiency while keeping the PCBs footprint at a minimum. To accomplish this there are a few wiring tips that you can keep in mind in order to keep a clean design that will help you achieve the functionality you need. Above three lines, it is a good idea to try to have line loops through each point so that your printed circuit board is easy to test and wire length is as short as possible. Be sure to place your components as neatly and uniformly as possible on your PCBs so that wiring can be completed in straight lines and at simple angles. This helps avoid wasted space on your PCB so that you can get the optimum usability from each layer.
