Send a drawing or specification — our engineers review it for manufacturability, quote it, and deliver tooled, tested laminated busbars. Every dimension, terminal and dielectric is configurable.
積層バスバーは、お客様の筐体、端子、電流ループを中心に設計されます。既製品は妥協を強います；カスタム積層バスバーは、層数、導体幅、誘電体厚さ、端子位置が図面と正確に一致するよう金型化されます – 1部品、ゼロ手直し。

The direction in high-current programs is that OEMs increasingly buy the laminated busbar not as a loose part but as part of a delivered subsystem — busbar plus connectors, flexible jumpers and cooling hardware integrated into one assembly. Reference market examples of this move are battery disconnect units (BDUs) for electrified powertrains and packaged power-conversion assemblies, where the supplier count shrinks and the line build becomes a drop-in installation rather than a harness build. For a custom laminated busbar design shop, this is the natural upward extension: the bar is already the backbone of the cabinet, so carrying terminals, jumpers and brackets along with it changes little at the drawing stage and a great deal on the customer’s floor.
The co-design principle behind it is that the busbar and its connector land are engineered together, not retrofitted. Industry datasheets specify the bar cross-section at every contact — for example a 38.1 × 4.8 mm copper land with an M6 thread at one frame size, and a 25.4 × 3.2 mm blade at another — and poles are paralleled in a single housing when a single contact cannot carry the current. Specifying the bar around the contact geometry is what makes blind-mate, hot-pluggable and service-friendly interfaces possible at all.
Four transferable design principles recur across this family of work:
When the joint itself moves — vibration, thermal expansion between module and bar — a flexible laminated jumper between rigid ends carries the motion without fatiguing the bolted joint, as explained in flexible laminated busbars. Whether you start from a drawing or from a current-path sketch, our DFM review turns the same principles against your layout; the process is outlined in the laminated busbar design guide, and reference stacked builds are shown under multi-layer insulated busbars.
