viaholeonderdelen

VIAHOLEonderdelen refers to the specific components and materials used in the fabrication of via holes on printed circuit boards (PCBs). A via is a conductive or non‑conductive passage that electrically or mechanically connects different layers of a multilayer PCBoard. VIAHOLEonderdelen encompass the metallization of the hole walls, the dielectric material inside, and any protective or conductive coatings applied during manufacturing.

There are several common types of vias used in modern electronics. Through‑hole vias penetrate the entire board thickness and are typically filled or coated with copper to ensure reliable conductivity. Blind vias connect two adjacent layers but do not traverse the entire board, whereas buried vias run between internal layers only. Microvias, which are much smaller (30–50 µm), are primarily used in high‑density interconnect (HDI) PCBs to achieve greater routing density and improved signal integrity.

The manufacturing of VIAHOLEonderdelen typically involves drilling or laser ablation to create the hole, followed by plating the walls with copper or another suitable conductor. In some high‑frequency applications, the via might be filled with a low‑loss dielectric to reduce parasitic inductance. After plating, a photoresist or protective coating may be applied to prevent oxidation and maintain component integrity during subsequent lamination steps.

Industry standards governing VIAHOLEonderdelen include IPC‑2221 for general PCB design, IPC‑2223 for board assembly, and IPC‑7351 for surface‑mount technology. Specifications such as via pitch, hole diameter, annular ring width, and plating thickness are crucial for ensuring manufacturability, reliability, and compliance with regulatory requirements like RoHS and REACH.

Common applications for VIAHOLEonderdelen are found in consumer electronics, telecommunications, automotive electronics, and aerospace systems, where multilayer PCBs provide the necessary density and performance. Vendors supplying these components range from PCB manufacturers that include via services in their fabrication process to specialized suppliers offering pre‑fabricated via modules or custom plating solutions.
