It wll I have close liaison with the Regional Centres for Transfer of Technology and other concerned organizations. Provincial Technical Advisory & Development Centres CPTADCs>: At the second tier of the technology network a number of provincial technical advisory and development centres CPTADCs) will be Initially established by the Federal Government as part of the National Technology Network. After successful operation for a couple of years they would be transferred to the Provincial Governments. These centres will have direct linkages vertically with the NCTT and also horizontally to the Industrial units In their areas. The functions of the PTADCs will be to provide facilities to Industries In their areas for design development and Improvement of products. provide essential common-user ser­ vices like heat treatment. electroplating. manufacturing of spare parts, technical Information and advanced practical training.
