The press-in zone of the AdvancedTCA® power connector is tested according to Telcordia/Bellcore GR 1217CORE Part7. It is approved to be used with a plated through hole according IEC 60352-5 with a diameter of 1.00 + 0.09 – 0.06 mm for signal contacts and 1.60 + 0.09 – 0.06 mm for power contacts (drilled hole 1.15±0.025 mm resp. 1.75±0.025 mm).

Based on our experiences regarding the production process of the PCB manufacturer we recommend a plated through hole configuration like shown in the above spreadsheet. To achieve the recommended plated through hole diameter, it is important to specify especially the drilled hole diameter of 1.15±0.025 mm resp. 1.75±0.025 mm to your PCB supplier.
