Industry-leading post-etch punch systems engineered for multilayer PCB fabrication. Micron-level repeatability, in-line inspection, and 40+ years of field-proven technology — now with dedicated North American sales and service.
Product Lines
Three distinct platforms to address every post-etch punching requirement — from cost-effective production to HDI-grade precision.
ECP-4000 / ECP-8000
Enhanced Capability Punch — Flagship Series
The highest-precision platform. HDI and mil-spec grade with in-line coaxial inspection, 4/8 camera vision, bronze bushing die set, and ±0.0003" repeatability.
ATP-7800
8-Camera High-Throughput Platform
Engineered for high-volume fabricators. 9+ panels per minute with backward compatibility for legacy Optiline systems. A clear upgrade path for existing users.
ATP-1000 / 3000E
4-Camera Automatic Post-Etch Punch
Fully automatic, cost-effective post-etch punching with 4-camera vision and 8+ panels/min throughput. Proven Multiline precision at an accessible price point.

Our Heritage
The original innovators of optical post-etch punching — now manufacturing the next generation.
Multiline Technology pioneered optical post-etch punching in 1983, establishing the industry standard for inner-layer registration in multilayer PCB fabrication. For decades, Multiline and Optiline systems were the benchmark equipment found in fabrication shops worldwide.
WKK represented Multiline across Asia for more than 30 years, building deep expertise in the technology and an extensive installed base. In December 2016, WKK acquired the global product rights to the entire Multiline Technology product line — including the ATP, OPE, and ECP series.
Today, WKK Machinery manufactures the next generation of Multiline systems from our advanced facility in Dongguan, China, incorporating modern Windows 11 platforms, SECS-GEM MES integration, and continuous precision improvements refined over four decades of engineering.
With the establishment of WKK America, we are bringing dedicated sales, service, and technical support to North American PCB fabricators for the first time.
