Is your multi-layer circuit board experiencing intermittent connections, signal loss, or other malfunctions due to via problems? Vias are essential for connecting different layers of a printed circuit board (PCB), and their failure can disrupt the board's functionality. ROC Industrial offers expert via repair services, restoring the integrity of your multi-layer PCB and saving you the expense of a complete replacement.
Understanding Circuit Board Vias
Vias are small, plated-through holes that connect different layers of a multi-layer circuit board. They allow signals and power to be routed between the various layers, enabling complex circuit designs. There are different types of vias:
Through-Hole Vias: Pass through all layers of the board.
Blind Vias: Connect an outer layer to one or more inner layers, but do not go all the way through the board.
Buried Vias: Connect two or more inner layers and are not visible from the outside of the board.
Microvias: Very small vias, often used in high-density interconnect (HDI) boards.
Common Via Problems
Cracked Vias: Thermal stress, mechanical stress, or manufacturing defects can cause cracks in the plating within the via, leading to intermittent or open connections.
Voiding: Gaps or voids in the plating within the via can also cause connection problems.
Poor Plating: Insufficient or uneven plating can lead to high resistance or open connections.
Pad Lifting: The pad around the via can lift or detach from the board, breaking the connection.
Corrosion: Moisture or other contaminants can corrode the via plating.

Our Circuit Board Via Repair Process
Free Evaluation & Quote: Describe the problem, the board type, and the number of layers (if known). Provide photos or X-rays if possible. We provide a free quote.Note: Via repair can be complex, especially for blind and buried vias. The feasibility and cost of repair depend on the specific board and the nature of the via problem.
Shipping: Ship the circuit board to our facility.
Diagnosis: Our technicians use advanced diagnostic techniques to identify faulty vias. This may involve:Visual Inspection: Using microscopes to examine visible vias.
Electrical Testing: Using multimeters and continuity testers to check for open or high-resistance connections.
Time-Domain Reflectometry (TDR): A specialized technique to locate faults in traces and vias.
X-ray Inspection: (If available and necessary) To examine internal vias (buried vias).Repair: Depending on the type of via and the nature of the problem, we may use various repair techniques, including:
Via Restaking/Re-drilling (Through-Hole Vias): If the via plating is damaged, we may be able to re-drill the via and re-plate it.
Jumper Wires: In some cases, we may be able to bypass a faulty via by soldering a jumper wire between the connected points on different layers.This is more common for through-hole vias and may not be feasible for all situations.
Conductive Epoxy: In some cases, conductive epoxy can be used to fill small voids or cracks in vias.Testing & Quality Assurance: We thoroughly test the repaired board to ensure that the via repairs have restored proper connectivity and that the board is functioning correctly. This may involve electrical testing, functional testing, and/or using specialized test fixtures.
Fast Turnaround: Minimize downtime.
Warranty: We offer a comprehensive warranty on all repairs.
