   We provide support to our customers by email. Our support staff are always ready to meet your needs.

    For fabrication to:                 sales@sinfopcb.com

    We are very responsive to email, usually within 24 hours. If there is no reply from us after one business day, a spam filter is likely to blame. We recommend resending your email from another account.
