Today I want to highlight some of the capabilities we have for manufacturing high reliability PCBs that can withstand extreme environments. Here are some key details on our process and quality:
PCB Material:
RO4350B hydrocarbon ceramic laminates are utilized which are lead-free and can be operated from -40°C to +85°C. This material provides excellent thermal performance and dimensional stability across a wide temperature range.
Stackup:
For rigorous applications, a 2-layer rigid PCB is often recommended with the following stackup:
35um finished copper is used
10mil RO4350B dielectric is used
35um finished copper is used
This provides good signal integrity and routing space while minimizing thickness.
Construction:
Dimensions are held to 29mm x 48mm with tight tolerances of +/- 0.15mm
Fine lines and spaces down to 7/7 mils can be achieved.
Minimum hole size of 0.2mm is used.
Board thickness is precisely controlled to 0.83mm.
1 oz (1.4 mil) finished copper weight is used on all layers.
1 mil plated through hole via thickness is used.
Immersion gold surface finish is used.
Quality and Testing:
No silkscreen is used to eliminate risk of contamination.
Solder masks are eliminated in high temp products.
100% electrical testing is used to ensure reliability.
Compliance to IPC Class 2 standards is maintained.
With capabilities like these, high reliability PCBs that meet the highest standards for quality and performance in demanding environments like aerospace, defense, and more can be delivered. Please contact us for more information or a quotation on your next project!
