HDI Printed Circuit Board
HDI boards, another of the highest technology in PCBs, also are accessible at Incredible. HDI Panels have blind and hidden visas and typically include MicroVAX of .006mm or below in size. They feature a greater circuit complexity than ordinary circuit boards. What is HDI PCB? HDI stands for High-Density Interconnector. Any SATA connector with a greater wire volume per square meter than a regular board is termed HDI circuit board. HDI PCBs feature narrower gaps and outlines, more minor visa and grab pads, and increased connecting pad frequency. It is beneficial in boosting electrochemical characteristics and lowering the shape and volume of ...
Work with PNC to Reduce PC Board Costs
When it comes to reducing the manufacturing cost of a PCB, it is important to remember that a significant part of the cost of a PCB assembly [1] is already baked in at the design concept stage. The product concept defines the PCB size and shape, while the performance of the system dictates the microprocessor, memory and other functional elements of the circuit. However, some of the assembly cost can still be affected by design choices made by the PCB designer. A PCB that is designed for manufacturing (DFM) can reduce both the fabrication cost of the PCB and the costs ...
Minimizing Crosstalk in PC Board Layout
In this ongoing series on PCB layout from the design team at PNC, previous posts have looked at some of the initial steps to turn a circuit schematic into a manufacturable, reliable PCB. These posts have looked at component placement [1], selecting appropriate trace widths [2], and BGA routing [3]. In this post we are going to take a deeper dive into methods for reducing crosstalk in the PCB design [4]. After the power and ground have been routed, the next task is to route high speed signal traces, and the traces that could either generate or receive crosstalk. What is ...
What are IPC standards for PCB Design, PCB Assembly and PCB Fabrication?
IPC standards are electronic design, manufacturing and inspection standards published by IPC, a global trade and standards setting association focused on the electronics industry. IPC’s standards are used worldwide and have been essential to the globalization of the electronics industry. Anyone who designs or manufactures PCB assemblies needs to be familiar with the standards. Most engineers and designers first encounter the IPCstandards in the fabrication notes on PCB drawings or because they have been trained on ubiquitous IPC-A-610 “Acceptability of Electronic Assemblies” which illustrates quality standards for PCB soldering and cleaning. The IPC publishes standards for every aspect of PCB design [1], ...
What’s a HDI Printed Circuit Board?
HDI stands for High Density Interconnect. HDI PCBs have finer traces and trace spacing, laser drilled micro vias and higher connection pad density. Its two chief advantages are that it permits the use of fine pitch BGAs and it reduces the number of PCB layers required because the finer traces and smaller vias allow more circuitry in a smaller area. Narrow trace widths mean higher circuit density At PNC standard PC Board fabrication [1] uses a minimum trace width of 5 mil, with a 5 mil space between traces (5/5mil) PNC’s HDI trace widths can be as narrow as 3 mil with ...
