Understanding PCB Assembly Repairs

BESTProto-understanding-PCB-repairs

Printed circuit board Assemblies are the brains of all of our modern electronic devices. Currently a 58 billion dollar industry, its worth is expected to grow up to 75 billion dollars by the year 2026. PCB Assemblies are so common in all of the devices we use every day that a failure causes us great inconvenience and even some personal stress.

There are times when a PCB Assembly will give some warning that it is about to experience a failure. For instance, a smartphone might display vertical lines or other distortions on the screen and a computer can give corrupt data warnings or reboot at random. The ultimate symptoms of PCB Assembly failure include overheating, smoke, an odor of burnt electronic components, and the failure of the unit to power up at all.

These are some of the most common reasons for PCB Assembly failures.

  1. Manufacturing defects – Misaligned layers, crossed signals, short circuits, and exposure to electrostatic discharge (ESD) are the most likely causes of PCB Assembly failure and generally occur during the PCB assembly process.
  2. Component burning – Caused by incorrect component spacing, component failures, errors made by the technician, and intense heat, repairing a burned component can mean replacing the entire PCB Assembly.
  3. The surrounding environment – PCB assembly is conducted in a clean climate-controlled area in order to prevent heat and humidity from causing the boards to expand and warp. After the board has been assembled and is being used for its intended purpose, external debris including liquid, fibers, dust, and hair can adhere to the PCB Assembly and cause it to overheat.
  4. Soldering errors – The consistency of the solder as it refers to its moisture content as well as application errors result in defects including excessive solder, cold joints, component shifting, and lifted pads.
  5. The PCB Assemblies’ age – The average PCB Assembly can last up to 10-20 years or more. As a PCB Assembly reaches its life expectancy, the electronic components begin to break down and require repair or replacement.

Repairing or replacing the components on a PCB Assembly is delicate work requiring expert precision. The technicians at BESTProto are supervised by master instructors in IPC A610 and JSTD-001 to guarantee that all PCBs we work on will meet current electronic industry standards. BESTProto offers the following PCB repair services:

  • Out of production/non-current electronic equipment and component repair
  • Re-box and re-label services
  • PCB troubleshooting and component level repair
  • PCB testing

Smart Homes are Being Made Possible by Fast and Efficient PCB Assembly

Untitled

The computer chip has revolutionized our daily lives in more ways than one. But it’s not just smartphones and laptops that are bringing us all closer together. Many of the machines we use on a daily basis are quickly becoming more connected with the help of cheap, printable computer chips.

Printed circuit boards (PCBs) have not only become more cost effective in the last decade, but they have also become much easier to prototype and design. What was once a strenuous process for large companies, requiring vast resources, can now be done with incredible precision and speed by specialized PCB company’s like BESTProto.

This revolution in PCB assembly has allowed companies to build smart technologies into more and more devices. Our cars look more like driving computers than the simple mechanical machines our parents used to operate. Washing machines, refrigerators, and even glasses that send a signal to the bartender when sensors indicate your drink is getting low all use this progressive technology.

These current trends in smart products have driven the rapid growth of the PCB, semiconductor, and other computing chips as more and more products continue to build themselves with smart technologies. Soon you may find that maintenance on your household appliances deals more with software updates than it does hardware updates.

The machines in our lives are learning to communicate with one another. This revolution in interconnectivity has also sparked a revolution in small computer chip manufacturing. Instead of expending vast resources on the design and manufacturing of computer chips, companies like BESTProto can now quickly prototype and build PCBs that make our lives safer, easier, and less wasteful.

PCB Assembly in Modern Medicine

Technology has facilitated the evolution of nearly every major industry within the past few decades. Today, one of the main electronic components in most medical equipment is the use of PCB, or printed circuit boards. These components act as the “brain” of any given electronic medical device.

The layout in modern PCBs is optimized for the task performed by the device. For example, most medical device PCBs are intended to be highly precise and quick. Because of the tremendous complexity of a PCB Assembly, most medical equipment companies today outsource the assembly and sometimes the layout and design to highly specialized third parties. The development of PCBs from scratch is a tedious and time consuming process, but specialized third-party manufacturers can often have PCB assembly prototypes ready within weeks.

Development of these electronic components can be traced back to the early 1900s, but it was not until the latter part of the century that they became reliable enough to implement in medical equipment. Older board assemblies were large and often did not work consistently. They had to be assembled by hand, which led to failure in most instances due to human error during assembly.
