The Hidden Gap Between a "Working" Schematic and a Shippable PCBAEvery hardware engineer knows the feeling. You spend weeks on the schematic. The components are perfectly selected, the power rails are clean, and the PCB layout passes every DRC (Design Rule Check) i2d ago · 4 min readanypcba.hashnode.dev
What Exactly Is Your Factory "Changing" on Your Board?Many hardware engineers share a habit: send the Gerber files, then wait for the boards to come back. The CAM engineering step in between? Rarely a concern. Until one day the boards come back different6d ago · 5 min readanypcba.hashnode.dev
How to Choose the Right HDI Order: 1-N, 2-N, Any-Layer—Higher Isn't Always BetterIn PCB design reviews, one question comes up again and again: how many orders of HDI does this board need? The answer is usually one of two extremes: "Let's try 1-N first," or "Just go any-layer, to bOct 13 · 5 min readanypcba.hashnode.dev
Via Stub Effects and Back Drilling in High-Speed PCBs: An SI Fundamental Every Hardware Engineer Should KnowIn high-speed digital design, signal integrity problems often hide in the least obvious places—vias.
