Chip packaging apparatus and terminal device

A chip packaging apparatus, comprising:

• a first differential pin pair, wherein the first differential pin pair includes a first differential signal pin and a second differential signal pin;
• a first pin;
• and
• a second pin, wherein
• the first pin and the second pin are located between the first differential signal pin and the second differential signal pin,
• the first pin and the second pin are differential signal pins or the first pin and the second pin are power pins,
• the first pin and the second pin are respectively located on two sides of a first imaginary straight line,
• the first imaginary straight line connects the first differential signal pin to the second differential signal pin,
• a first auxiliary line intersects the first imaginary straight line at a position of the first differential signal pin and along a direction perpendicular to the first imaginary straight line,
• a second auxiliary line intersects the first imaginary straight line at a position of the second differential signal pin and along the direction perpendicular to the first imaginary straight line,
• the first pin and the second pin are symmetrical about a first symmetrical point,
• the first differential signal pin and the second differential signal pin are symmetrical about the first symmetrical point
• a first included angle γ1 exists between a second imaginary straight line and a zero potential plane,
• the second imaginary straight line connects the first pin to the first symmetrical point and the zero potential plane,
• a second included angle γ2 exists between a third imaginary straight line and the zero potential plane,
• the third imaginary straight line connects the second pin to the first symmetrical point and the zero potential plane,
• a spacing, along a horizontal direction, between the first differential signal pin and the second differential signal pin is less than a spacing, along a vertical direction, between the first pin and the second pin,
• the first included angle γ1 is 5° to 15°,
• the second included angle γ2 is 5° to 15°,
• the first pin and the second pin form a second differential pin pair, and
• a differential signal transmitted by the first differential pin pair and the second differential pin pair do not interfere with each other.
