What is Array
In the PCB industry, an array refers to a grouping or combination of smaller-sized individual circuit boards that are connected together to form a larger array of circuits. This practice is employed to optimize the utilization of the panel on which the circuits are printed and to minimize wastage. By printing multiple copies of the same circuit on a single panel, manufacturers can maximize the number of circuits produced while minimizing material waste.
The concept of an array is particularly relevant when dealing with circuits that are significantly smaller in size compared to the panel on which they are printed. Instead of printing each individual circuit separately, an array allows for the efficient printing of multiple circuits on a single panel. This approach is especially beneficial in terms of time and cost savings during the assembly process.
The use of board arrays on large panels is facilitated by modern assembly machinery that is equipped with sliding rails. These rails can accommodate the PCB panels, allowing for the simultaneous processing of multiple circuits. This eliminates the need to move smaller individual boards along the rails one by one, which would significantly increase the time required for component placement.
Frequently Asked Questions
What Is the Size of the Array in PCB
Array sizes in PCB can vary, but the overall largest size typically ranges from 8 x 10 inches to 10 x 12 inches. However, it’s important to note that the actual size of the array will depend on the production panel size and usable space provided by the PCB manufacturer. For example, if the production panel size is 18×24 with a usable space of 16×22, the best fit for the largest array would be approximately 7.8 x 10.8 inches.
What Is a PCB Layout
PCB Layout is a sophisticated engineering software used for designing circuit boards. It offers intelligent manual routing for high-speed and differential signals, an advanced shape-based autorouter, extensive verification tools, and the ability to import and export designs easily.
What Is the Difference Between PCB Panel and Array
A PCB panel, also known as a PCB array, is a single board that comprises multiple individual boards. After assembly, the panel is subsequently separated, or depanelized, into the individual PCBs during the breakout procedure.
