High Density Interconnect (HDI) PCB’s

HDI technology is rapidly expanding in the PCB world. This technology allows significantly denser and smaller board construction and packaging allowing for substantially more components per square inch. Basically, it’s more technology-functionality in less space. HDI has proven invaluable and critical in the production of electronic equipment with smaller and tighter space. Cell phones, laptops, and high speed performance and computing would not be possible without HDI as we know it today

Examples of HDI technology include fine lines and spaces, sequential lamination, back-drilling, non-conductive and conductive via fill, blind vias, buried vias, and microvias. These are specifically PCB technologies that are allowing tight and miniaturized packaging. They also allow higher levels of performance like controlled impedance and satellite technologies.Designing and

manufacturing HDI PCB’s come with an increased cost, but one that must be embraced and mastered to meet the ever demanding requirements of the Electronic Industry.

South Bay Circuits is here to meet your HDI PCB needs.

Drastically Reduce New Product Integration (NPI) Time: Step 5 of 5

Drastically Reduce New Product Integration (NPI) Time: Step 5 of 5


Processing/manufacturing in-parallel rather than in-series.


Specifically: Orders for components and materials should be placed by your supplier prior or at the time pc bare board manufacturing starts. This will help insure components and materials are ready for assembly when the pc bare boards are completed. Additionally utilizing a company that controls the entire process: layout through assembly will provide the added benefit of single source accountability, improved delivery, and performance.

Summary: Following the 5 Key Steps to Slashing NPI time saves both time and money. It creates the option to get deliveries in historic timeframes at reduced costs or more importantly significantly faster for the same cost.

What is a PCB

What is a PCB

Have you ever opened up your computer or phone? The PCB or printed circuit board is the flat, typically green, piece that holds all the chips and/or electrical components. Below the green solder mask/overlay, are wires/traces on the board. They connect the components, creating circuits.

A PCB that has yet to have any electrical components soldered onto it, is called a “bare board”, or more properly, a “printed circuit board”. There are however copper traces called "wiring" that have been created by printing, plating, and etching processes.

To produce a PCB you need to take the functional diagram or schematic and transform it into a piece of artwork that makes a pattern for components, holes, and circuits/wires. The PCB designer is the engineer who creates the schematic. It is similar to the plates used in printing, although technically quite different.

PCB’s range in size, and are used in a multitude of products way too extensive to list, but here are a few: cell phones, autos, computers, TV’s, flash drives, thermostats, vehicles, weapons, and video game consoles. If it’s electronic, a PCB is probably the board holding the brains behind it.

South Bay Circuits: ITAR Registered

South Bay Circuits: ITAR Registered


The US Government expects all producers, exporters, and dealers of defense articles, defense services, or similar technical information to be ITAR registered. To satisfy this OEM’s are requiring their supply chain members be ITAR REGISTERED. You will typically find language contained in contracts, on purchase orders, and request for proposals stating this requirement to meet: The International Traffic in Arms Regulations (ITAR). Communicating with staff members of the Directorate of Defense Trade Controls (DDTC) may get slightly different answers, but the generally accepted definition is:

For a company involved in the manufacture, sale or distribution of goods or services covered under the United States Munitions List (USML), or a component supplier to goods covered under the USML, the stipulation or requirement of being “ITAR certified (compliant)” means that the company must be registered with the State Department’s DDTC, if required as spelled out on DDTC’s web site and the company must understand and abide by the ITAR as it applies to their USML linked goods or services. The company themselves is certifying that they operate in accordance with the ITAR when they accept being a supplier for the USML prime exporter. 

Simply stated, to be ITAR COMPLIANT, you need to be registered with DDTC and understand the requirements to be in compliance with ITAR, and self-certify that you meet the standard.

ITAR can be found at: ITAR Regulations

South Bay Circuits (SBC) is registered and complies with the DDTC and the ITAR requirements.

Drastically Reduce New Product Introduction (NPI) Time: Step 1 of 5

Drastically Reduce New Product Introduction (NPI) Time: Step 1 of 5

The PCBA phase of new product introduction can be significantly reduced by following 5 logistic steps.

Step 1: Organize the process & develop a materials list:

This step has a dual approach in the design phase.

  • Determine critical components
  • Create a process checklist

First, gather a list of your critical/specialty components and determine their availability. You could use a web service like https://www.eciaauthorized.com/en for example. Knowing when materials will be available provides a clear timeline for product introduction.

Second, create a footprint of the process. Map out each phase of the project from design to mfg. This will flag issues early and provide the opportunity to address and resolve in a timely manner.

Get your suppliers engaged up front, particularly if unique and/or undefined aspects to your design exist. A lower cost, higher quality product will be your reward. Saving time and money should not be an option.
