The Big Questions About PCB Manufacturing: What Is a “Positive Film”? What Is a “Negative Film”?

Wherever electronic products exist, PCBs (printed circuit boards) are indispensable. Industry veterans often mention “positive film” and “negative film.” If you're as confused by these terms as I was when I first entered the field as a rookie 20 years ago, let's discuss the differences between these two manufacturing processes today.

Three Major Models in PCB Manufacturing: Technical Applications and Control of OEM, ODM, and OBM

Within the electronics manufacturing ecosystem, OEM (Original Equipment Manufacturer), ODM (Original Design Manufacturer), and OBM (Original Brand Manufacturer) represent three distinct yet interconnected business models. These models differ not only in their operational structures but also exhibit significant variations in the application of PCB processing technologies, key management considerations, and value creation.

PCB Information - Why Are PCBs Almost Always “Green”?

The PCB substrate itself is actually pale yellow; the green we see is the color of the solder mask. Green became the industry standard because it offers the best visibility for engineers, the most mature and stable manufacturing process, the lowest cost, and the highest contrast during inspection, making it easier to spot defects. So this “green” is truly the culmination of time-tested wisdom!

mSAP and SAP Process Analysis: Key Processes for Forming Fine Lines in High-Density Circuit Boards

To overcome the side etching issues inherent in traditional subtractive processes, semi-additive processes (SAP) and modified semi-additive processes (mSAP) have emerged as the mainstream technologies for IC substrates and substrate-like substrates (SLP). SAP utilizes electrolytic copper as its substrate, delivering the highest circuit precision. mSAP, employing ultra-thin copper foil, strikes a balance between precision and cost, making it a highly cost-effective choice.
