4 Layer Delay
Our fabricator primarily responsible for handling our 4 layer orders has had a stock interruption, making our typical FR408HR (core and prepreg) unavailable. Replenished stock is expected around Sept 28th, meaning no FR408HR boards will be shipping until at least Oct 2nd.
Until stock availability is restored, we will be offering an alternate stackup, detailed here: EM528 Stackup. This stackup can be selected for 4 layer boards during checkout as the “EM528 Compatible” option. It can also be requested via email if you change your mind.
Orders that do not request EM528 will be held FR408HR is available, and fabbed with our typical stackup.
Our apologies for any disruption this may cause.
