IPC-2226 defines HDI as a printed circuit board with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces ≤100 µm / 0.10mm, smaller vias (<150 µm) and capture pads <400 µm / 0.40mm, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology.
Consider the PCB signal as it travels along a track controlling impedance means that we control the performance or speed of that signal at a point along a track. Related to resistance, capacitance and conductance of the track in question. The impedance is also measured in Ohms, it is different than resistance which is a DC characteristic. Impedance is an AC characteristic, meaning that it is related to frequency.
The preferred type of plugging for standard product (not including capped via hole) is IPC 4761 type VI filled and covered, with target being complete fill. The image below shows type VI with liquid soldermask coverage.
Single sided plugging is not recommended (including type II tented and covered) due to concerns over entrapment of chemistry or likelihood of solderballs being present with HASL finishes (LF and SnPb).
Substrate materials affect PCB performance through their electrical properties, including dielectric constant and loss, which influence signal integrity. Thermal conductivity is key for heat management, and mechanical strength impacts durability. The right choice ensures optimal PCB operation.

PCB assembly is the process of placing and soldering electronic components onto a printed circuit board (PCB) to create a functional electronic device. This process uses techniques such as through-hole, surface-mount technology (SMT), or a combination of both (mixed technology).
We ensure top-quality PCB assembly with ISO9001, ISO14001, IATF16949, ISO13485, and ISO17025 compliance. Our process includes AOI for defect detection, X-ray for BGA solder verification, conformal coating for protection, and ICT to ensure flawless functionality.
Surface-Mount Technology (SMT): A fast, automated process where components are soldered directly onto the PCB’s surface. It is efficient and suitable for high-volume production.
Through-Hole Technology: Involves inserting component leads through pre-drilled holes in the PCB and soldering them on the reverse side. This method is slower but offers stronger mechanical bonds, making it ideal for heavy-duty applications.
Yes, we provide full turnkey services, managing the entire production process from component sourcing and procurement to assembly and quality testing.
