ASM SIPLACE 03058631 is the complete Z-drive assembly used in the C&P20A placement head. It belongs to the head's Z-axis linear guidance system, and 03058631-02 is a documented revision in the spare-parts market. The related C&P20A placement head can also be identified by the blue marking on its Z-axis rotor.
Do not match this assembly by Z-drive function alone. The earlier C&P20 head uses 03005155-xx, while C&P20A uses 03058631-xx. X-Series machines may use either head family, so the machine model alone is not enough to confirm the correct Z-drive.

Z-axis alarms or irregular head movement do not automatically mean that the 03058631 assembly has failed. Typical inspection reasons include inconsistent Z movement, abnormal resistance or noise around the Z guidance, repeated movement-related alarms, or failure to complete normal Z-axis motion.
First, confirm the C&P20A head identity and complete drive label. Then inspect the Z-axis guidance, visible connections and surrounding mechanical path for binding, contamination, looseness or abnormal resistance. Only after these checks should the complete Z-drive assembly be isolated as the replacement target.
If the fault or revision is unclear, send the complete 03058631 label, head identification, machine model, installation photos and a short video of the abnormal movement for matching before replacement.
03058631 is normally available from stock, with confirmed orders usually dispatched within 24–48 hours. Urgent line-repair orders can be prioritized. Send the complete part label, head model, machine model, required quantity and installation photos for compatibility verification and formal quotation.
