This 2-layer FR-4 board measured 169 × 411.67 mm with 1.6 mm thickness, TG150 material, and 1 oz copper on both sides. Produced as 60 pieces in 1×4 panels for 15 sets, the order specified lead-free HASL surface finish, cold white solder mask, and black silkscreen. Line/space remained at standard 10 mil with 0.4 mm minimum holes, and the 2-day schedule included 100% flying probe testing together with routing separation. Customer notes called for consideration of IPC Class 2 requirements.
DFM review addressed three process points. Multiple holes larger than 3 mm required confirmation of whether precision routing was needed to maintain positional accuracy and edge quality. Connection tabs in the panel data lacked mouse bites, which could lead to difficult or incomplete depanelization; standard stamp holes were reviewed for addition. Dimensional tolerances were aligned to factory conventional values, with any conflicting notes disregarded after confirmation.
Confirmed adjustments to hole processing and panel tabs were implemented prior to production. The boards achieved consistent lead-free HASL coverage and clean routing results within the short delivery window. Full electrical test reports and quality certificates accompanied the shipment, confirming the panels met the specified mechanical and electrical criteria for IPC Class 2 consideration.
