110 I-CONNECT007 MAGAZINE I MAY 2026 This can create challenges with lead times and yield, and potentially jeopardize production of the boards. Designers should clearly define the non- conductive via filling requirement in the Gerber files and confirm the manufacturer has the proven ability to build the PCB to specs. More information is always better when submit- ting quotes. We encourage designers to include as many specifics as possible in their quote re- quests. This can include specifying non-conductive material used for via filling, identifying the type of surface finish needed to ensure a flat pad for as- sembly, and defining any other key manufacturing considerations. Working Closely With Your PCB Manufacturer When designers call out production specifications in detail, manufacturers do not have to guess what the designer wants. Collaboration also serves to minimize ambiguity about expectations during the quote process and before PCB manufacturing takes place. Open communication helps the de- signer and manufacturer align priorities based on what is required at any given stage of the lifecycle, from early prototyping to final prototype to full production. Collaboration also helps the designer under- stand the experience level and capabilities a man- ufacturer possesses regarding a capability such as NCVF. Not all manufacturers take the same approach to the process. Don't be afraid to ask to speak to members of the production team. Doing so can help you better understand the manufac- turer's approach and align expectations for things like lead time, cost control, and board functionality. Talking to individuals on the production floor, such as engineers or team leaders, will give you more confidence in the manufacturer's ability. The more designers know about a manufactur- ing technique like NCVF, the better they can craft quotes that ensure their designs are built to spec.
