Since China’s National Day is approaching, we’d like to inform you that we’ll have an eight-day holiday from Oct. 1st to Oct. 8th (GMT+8) during which your question or email may not be replied immediately. However, quotation or orders can be submitted online as usual.

In order not to get your manufacturing efficiency reduced, we strongly suggest you submit quotation or order in advance so that manufacturing can be done or started at least before our public holiday. We’ll be back at your service on Oct 9th.


For PCB orders, please kindly calculate the lead date before you place the order. Some orders cannot be finished before our holiday and will be delayed to October.
