IN Brief:
- Ventec and MICAM are developing a joint venture to manufacture copper-clad laminates at MICAM's existing facility in Mallow.
- Test pressing and pre-production are planned for Q1 2027, with full production capability targeted for Q2.
- A proposed second phase would introduce prepreg treating equipment, extending the Irish site's PCB materials capabilities.
Ventec International Group and MICAM are developing a joint venture to manufacture copper-clad laminates at MICAM's existing facility in Mallow, Ireland. The project would establish an additional European Union source of printed circuit board materials for defence electronics and other applications requiring dependable supply and controlled material characteristics.
Equipment installation is under way for the first phase, which will introduce copper-clad laminate pressing capability. Test pressing and pre-production are scheduled for the first quarter of 2027, followed by a target of full production capability during the second quarter. A subsequent phase could add treating equipment for manufacturing prepreg materials.
Ventec specialises in copper-clad laminates and prepregs used in PCB manufacture, with established production operations in Taiwan and China. MICAM produces advanced composite materials for industrial, security, and defence applications. Locating the proposed operation within an existing Irish manufacturing facility provides an alternative to constructing an entirely new site, although the partners have not disclosed the investment required or the capacity being installed.
Copper-clad laminate forms the structural and insulating base of many rigid printed circuit boards. Reinforcing materials and resin systems are consolidated with copper foil to produce sheets that can be processed into electronic circuitry. During PCB fabrication, the copper is patterned to form conductive tracks, while further processing can add drilled and plated connections, multilayer structures, and the features required for component assembly.
The material's electrical properties influence signal behaviour within the completed board. Dielectric constant and dissipation characteristics affect the propagation and attenuation of electrical signals, particularly as transmission frequencies increase. Thickness consistency, dimensional stability, and adhesion between the copper and insulating materials also influence manufacturing quality and long-term performance.
Thermal properties become important when a PCB is exposed to repeated temperature changes or elevated operating conditions. Differences in expansion between materials can produce mechanical stresses at interfaces, plated connections, and component joints. Laminates intended for demanding applications must therefore be selected alongside the circuit design, fabrication process, assembly temperatures, and intended service environment.
The planned Mallow operation will initially concentrate on laminate pressing. This process applies controlled temperature and pressure to consolidate the constituent layers and establish the required physical structure. Resin behaviour, pressing conditions, and cooling influence the resulting laminate, making process consistency important when customers require repeatable material performance.
Prepreg manufacture would add a different stage of the materials process. Prepreg typically consists of reinforcing fabric impregnated with a partially cured resin system, providing bonding and insulation between layers during the manufacture of multilayer PCBs. Its resin content, flow characteristics, and curing behaviour affect the quality of the completed board.
Ventec and MICAM intend to evaluate that capability in a second phase, using additional treating equipment. The partners have not announced a confirmed installation date or production start for prepreg, and it remains a planned extension rather than part of the initial operating capability.
The companies are positioning the Irish project around supply requirements for defence electronics. Programmes involving long service lives and controlled manufacturing specifications can place considerable importance on material provenance, traceability, and the continued availability of qualified products. Replacing an approved laminate may require additional technical evaluation even when an alternative appears to have similar headline characteristics.
Regional manufacturing capacity can provide another sourcing option, particularly when logistics disruption or changes to international trade arrangements affect existing supply routes. It does not automatically remove dependence on imported raw materials, however. Copper foil, reinforcing materials, resin constituents, and other inputs must still be obtained from suppliers capable of meeting the required specifications.
Mark Goodwin, Ventec's Chief Operating Officer for EMEA and the USA, described the initiative as part of efforts to strengthen European defence electronics supply. He said: "Security of supply starts with the materials."
The project follows Ventec's investment in a separate manufacturing facility in Thailand, which the company opened in October. That expansion added capacity in Southeast Asia, while the proposed Irish venture would establish production within the EU. Both form part of Ventec's strategy of diversifying manufacturing beyond its established operations in Taiwan and China.
Jason Chung, Chief Executive Officer of Ventec International Group, said the Irish development would provide customers with an additional manufacturing option for materials used in defence programmes. The project has not yet been accompanied by a published list of intended material grades, customer qualifications, or expected annual output.
Those details will determine the range of PCB manufacturing applications that the Mallow facility can support. Qualification of a new material production site may involve testing of electrical, thermal, and mechanical characteristics, together with evidence of process control and consistency between manufacturing batches. Existing product approvals cannot be assumed to transfer automatically to a new factory.
The partners expect to provide further information about the product range and second-phase investment as the venture progresses. Initial equipment installation is already taking place, but the production timetable remains prospective. The next operational milestone is test pressing in Q1 2027, ahead of the planned transition to full laminate production capability in Q2.
