How important is the communication of the use of precision stamping parts [hardware]

Ms. Zhou of customer A006733 sent a drawing of precision stamping parts used on the router. The appearance size is ±0.02mm, the hole position is required to be ±0.01mm, and the corner is a bent position, the drawing only marked ±0.05mm. The drawings seem to be okay. Engineer Zhao Gong, who has 15 years of experience, didn't pay much attention to this detail at the beginning, but found a problem when designing the mold drawing. If the bending position is 0.05mm according to the drawing, if the structure of the bending position is affected by the device, the tolerance of one wire in the hole position becomes meaningless. So Mr. Zhao immediately met with Mr. Zhang, the customer's design project, and expressed his concerns. Zhang Gong also quickly sent the circuit board diagram to everyone to study together, and it happened to have a positioning column design at the bending position of this precision stamping part. If this positioning column also has a tolerance, then these data will be affected. The problem is solved before the problem occurs. Hardware, work hard, worthy of your trust, phone:
