March 18 (Reuters) - Shenzhen-listed Delton Technology (Guangzhou) 001389.SZ, 1989.HK has priced its Hong Kong listing at the maximum offer price, raising around HK$3.31 billion ($422.27 million), an exchange filing showed on Wednesday.

The printed circuit board maker set the final offer price at HK$71.88 for each of the 46 million H shares in the offering, according to the filing.

Further details such as the results of allocations, indications of interest and applications received will be announced on Thursday, the company said.

Trading in Delton's Hong Kong shares is set to begin on March 20.

Delton joins a string of mainland China firms listing in one of the world's premier capital markets. Hong Kong was 2025's top listing venue globally.

Hong Kong's stock exchange is also seeking to lower thresholds for dual-class share listings, which could fuel the boom in initial public offerings.

However, Beijing is restricting certain Chinese companies incorporated overseas from seeking listings in Hong Kong unless they change their domiciles back to China, which could limit this momentum.
