diesmith develops and supplies precision machined components for semiconductor equipment — and the leadframes, precision dies, and stamped parts behind advanced packaging. Quoted and managed from the US — manufactured by Dongho A-Tech, our production partner in Busan, Korea, on a precision base built since 1994.
From vacuum-chamber hardware to the leadframes inside the package — machined, stamped, and molded to print on an integrated production base.
Centering & locating studs, retainer and clamp rings, spacers, bushings, and precision fasteners for process and vacuum chambers. Machined to print, inspected to spec, documented per lot.
Semiconductor and LED leadframes — including 10SSOP 7-row and 48TSSOP 4-up formats — plus connectors and fine-pitch stamped parts, produced on progressive dies built at the same facility.
A dedicated die design laboratory (operating since 1998) and a proprietary automated leadframe die design method at our partner's Busan facility. The tools are built where the parts are run — so design changes move in days, not months.
Die design through inspection under one roof at Dongho A-Tech, our Busan production partner — with an affiliated plant in Malaysia. One owner of quality from the first drawing to the packed lot.
Dedicated design laboratory; proprietary automated leadframe die design.
Precision dies for leadframes, connectors, and post-process packaging.
Progressive stamping and CNC machining of production parts.
Automotive, high-reliability, and appliance precision moldings.
Dimensional reports, material certs, and full lot traceability.
