PCBs for Computers & Computing Applications

Computing PCB Manufacturing & Assembly

Advanced Computing Applications

The computing industry has seen rapid growth over the past few years from personal computer devices like tablets and smartphones to high performance computing like crypto-mining and deep learning servers.

None of these advancements would be possible without ever-advancing PCB technology and HDI circuits staying ahead of this growth.

Your PCB fabrication and assembly partner needs to stay on top of board technology trends and meet industry standards for the highest level of computing possible.

As this industry continues to experience rapid growth, the manufacturing and design standards for computing electronics are consistently being updated and shifting. It is critical to work with a company who can manufacture bareboards and assemble PCB components to your specifications while also staying within standards, like those set by the IPC.

Standards & Guidelines for Computing

IPC is the trade association for the electronic interconnection industry. IPC provides industry standards for training, market research, public policy, and, most importantly, assembly and protection of electronic components.

IPC is a member-driven organization with over 3,000 member companies including designers, suppliers, board manufacturers, assembly companies, and original equipment manufacturers.

Meeting IPC standards for the computing industry affects the planning and designing of your PCB parts and even the testing and quality assurance of final PCBs.

San Francisco Circuits has provided computing PCB fabrication and assembly adhering to many standards for different uses within the industry. For example, all computing devices are tested by IPC-TM-650 standards.

IPC-TM-650 provides rules for evaluating PCBs in many categories.

Examine method IPC-TM-650 2.6.14.1, for example, provides how to test a board's propensity for surface electrochemical migration. This test determines the resistance to current flow over a PCB substrate surface. The IPC-TM-650-2.3.25.1 standard defines a technique for assessing the ionic cleanliness of bare printed wiring boards, which is significant since ionic contamination can cause problems that lead a PCB to fail.

Best Practices for Computing Device Layouts

With the majority of devices used in computing being interconnected and constantly communicating with one another it is best to closely follow good PCB practices. Standardized planning, designing, fabrication, and assembly are the key to compliant PCB components.

These help prevent board-level faults which could prevent compromising entire computing systems.

This makes following these best practices vital to the essential functions of the computing devices and the systems they are attached to:

  • Use materials outlined in IPC-4101C
  • Use correct grid spacing
  • When possible, avoid multiple grids
  • Keep trace lengths and sensitive signals as short and direct as possible
  • Keep traces as wide as possible within the PCB layout for maximum current signal bandwidth
  • Use power planes and ground planes to shorten decoupling capacitor signals and provide good ground coverage
  • Do not break the ground plane at all costs
  • Build in enough copper for high power dissipation and minimized voltage drop for high energy traces/planes
  • Compare against standard IPC design rules as often as you can
  • Use silkscreens to make the entire process easier
  • Stay away from auto-routers as often as possible
  • Carefully following IPC-2581 while designing and communicating PCB plans

Testing & Inspection Guidelines

Beyond the design and fulfillment process there are many stages of testing PCB components before being seen as the final product, including:

  • High impact testing
  • Water submersion
  • Peel testing to determine how easily the laminate can be removed from the board
  • Solder float test to see how much thermal stress the PCB can withstand
  • Any other harsh environmental testing that may be relevant to the application
  • IPC-A-610, which provides the final criteria for all end products to meet and is considered the final step in the PCB process
  • Bare and functional level testing
  • In-Circuit Testing
  • Automated optical inspection to detect mistakes early-on in the manufacturing process
  • Burn-in testing to check limits and safety features of PCB designs
  • Impedance Testing
  • X-ray inspection for non-visible solder joints

Catastrophic failures in the field can not only destroy the particular device the faulty PCB is in, but it could damage the other computing systems the PCB is interfacing with.

By taking the time to assess risks within each design with a thorough testing and inspection process, we are able to make sure that each potential hazard has been addressed and tested against.
