The invention discloses a hot platen die design capable of resisting the collision between welding pins, and the design is that a wedge-shaped opening surface is additionally provided with a right-angle step, thereby prolonging the spatial distance in a back welding direction on the basis that the width of an opening is not increased, enabling the welding pins and a platen to form a certain spacetherebetween so as to protect the welding pins from being broken. The design is used for the long line arc welding between chips. In a welding process, the welding direction is from a left chip to a right chip (or from the right to the left). When the line arc welding length is too long, the right-angle slotting prolongs the distance between the wall of the platen and a bonding pad while the position of the front end of the platen is not changed, thereby effectively preventing the collision between the welding pins and the platen. The design can solve an abnormal problem that the welding pinsare broken because of the collision with the wall of the platen in a chip packaging and wire welding process in a super-long conventional line arc design.
