Ventec has announced that its VT-901 polyimide material is now fully and exclusively qualified by ESA in ACB Belgium’s manufacture of High-Density Interconnect (HDI) PCBs.

With this recently obtained ESA qualification, ACB is currently the only PCB manufacturer able to offer HDI technology within an ESA qualified domain.

Ventec's VT-901 polyimide material offers exceptional reliability performance, meeting the demanding requirements of ACB's HDI PCB manufacturing process that adheres to ESA standards. It has a high Td of 395°C, a Tg of 250°C, and a Low-Axis CTE of 50.

Ventec manufactures all VT-901 polyimide using custom treaters equipped with advanced filtration systems and 100% Automated Optical Inspection (AOI) to ensure strict FOD-control and adherence to the IPC4101E Appendix A inspection standards for materials for space applications. The same specialised equipment is utilised to manufacture thin-core laminates that are specifically designed for the most challenging space and aerospace printed circuit board applications. ACB's advanced PCB manufacturing plant in Dendermonde, Belgium, together with Ventec's AS9100 Rev D accreditation for their manufacturing and distribution facilities, establish both firms as leaders in the supply of space and aerospace electronics.

Joachim Verhegge, ACB Belgium's Plant Director, says: “Further to our already existing ESA approval for Ventec’s VT-901 polyimide material in our Sequential Rigid and Rigid-Flex applications, we are pleased to now receive our ESA HDI technology qualification. This latest approval further reaffirms our position as a top-tier PCB manufacturer for the next generation of space programs.”

Peter Coakley, Ventec Director of Sales EMEA, commented: “We have a long-standing technology partnership with ACB, and I'm happy to support them in further strengthening their position as a leading provider of aerospace-standard PCBs. Ventec VT-901 polyimide's thermal resilience and suitability for usage in high reliability rigid and flex rigid multi-layers in the demanding aerospace sector are demonstrated by the most recent ESA approval for HDI Rigid applications.”

Ventec International is a world leader in the production of polyimide & high reliability epoxy laminates and prepregs and specialist provider of thermal management and IMS solutions.
