MEP EP#331: The PCB PlagueNeutrik EtherCON Ruggedized RJ45 Lockable RJ45 cable within an XLR style housing Also come in a sealed version that offers IP65 rating Interesting PCB failures “The Plague” Black Pad Very poor to no solderability Effect of Moon Phase on Tombstoning Many factors play a role in the overall outcome of PCB assembly, especially when very small components are involved. Broadly speaking, tombstoning is a problem with very small 2-pin components (0201 caps and such) and we've filtered out the following challenges: - proper paste application - component placement - designing for "good" thermal properties of the PCB with regard to tombstoning - moon phase Stretching Stainless Stencils? Oddity Today Interesting manufacturing defect surfacing Stencil “stretches” ever couple panels or so Anyone ever seen or experienced this before? Solutions? Next Steps?
