Recommended configuration of plated through holes har-bus® HM male connector CompactPCI In addition to the hot-air-level (HAL), other PCB surfaces are getting more important. Due to their different properties - such as mechanical strength and coefficient of friction - we recommend the following configuration of PCB through holes. Drilled hole Ø Tin plated PCB (HAL) acc. to EN 60352-5 General information Design Chemical tin plated PCB IEC 61076-4-101 0,7±0,02 mm Cu min. 25µm Sn max. 15µm plated hole Ø 0,60 – 0,65mm Drilled hole Ø 0,7±0,02 mm Cu min. 25µm Sn min. 0,8µm No. of contacts 55 - 220 signal (77 - 308 fully shielded); or customised plated hole Ø 0,60 – 0,65mm Contact spacing 2,0mm Drilled hole Ø 0,7±0,02 mm Test voltage 750V AC Cu min. 25µm Contact resistance 20 mOhm max.

Drilled hole Ø 0,7±0,02 mm - PL1 acc. to IEC 61076-4-101 => 500 mating cycles - PL2 acc. to IEC 61076-4-101 => 250 mating cycles UL file E102079 RoHS - compliant Yes Leadfree Yes Copper plated PCB (OSP) Cu min. 25µm plated hole Ø 0,60 – 0,65mm Circuit density Insulator material Material PC (Polycarbonate, glass fiber reinforcement 20%) Color RAL 7032 (grey) UL classification UL 94-V0 Material group acc. IEC 60664-1 IIIa (175 < CTI < 400) NFF classification I2, F1 When using the specified diameter of the finished through hole according to IEC 61 076-4-101 (0.6 ± 0.05 mm) with an appropriate annular ring, the remaining distance between the rings is about 1 mm. Under the condition that the width of the track and the space between should be equal, two tracks of 0.2 mm width or three tracks of 0.14 mm width can be placed between two rings. Typical designs are shown in the drawing on the right side.

The current capacity curve is valid for continuous, non interrupted current loaded contacts of connectors when simultaneous power on all contacts is given, without exceeding the maximum temperature.
