About Us
Dongguan Zhengyu Technology Co., Ltd. is a leading one-stop PCB equipment and laboratory turnkey solution provider. We deeply specialize in two core areas: PCB production pressing and quality control testing, serving thousands of electronics and material manufacturers across China.

Three Core Product Lines
We cover the entire PCB workflow from mass production to micro-failure analysis:

PCB Hot Press Series: Vacuum laminators and FPC coverlay hot presses featuring precise control over temperature, pressure, and vacuum to ensure high yield and eliminate defects like bubbles or warppage.

PCB Testing Instruments: A complete range of testing tools (including gel time, resin fluidity, and peel strength testers) for IQC, in-process inspection, and final quality control to prevent batch defects.

Metallographic Sample Preparation Equipment: Precision cutters, mounting machines, and automatic polishers that deliver IPC-compliant micro-sections for failure analysis, coating thickness testing, and defect tracking.

Why Choose Us
Equipped with an expert R&D team combining PCB processing and mechanical engineering, all our machines are built for heavy-duty industrial工况 (working conditions) and undergo 72-hour continuous aging tests. We offer non-standard customization, factory layout planning, on-site installation, and rapid-response technical support to help the electronics industry cut costs and upgrade processing technology.
