Iyo sosiyete ifise uburebure bwa metero kare 26680, ifise abakozi barenga 380 n’abahinga n’abahinga 57. Iyi sosiyete yashinzwe mu 1989. Yaciye icemezo ca ISO9001 c’uburyo bwo gucunga neza (SGS) mu 2002. Ibintu vyose n’ibikoresho vya mbere bihuye n’ibisabwa vy’ibidukikije vya eu ROHS. Mu mwaka w’2005, yaratsinze ikigo c’intara ya jiangsu c’ubuhinga n’ubuhinga bwigenga, muri uwo mwaka nyene yaratsinze kandi igihembo c’ubuhinga bushasha bwigenga, ikigega co gufasha mu guteza imbere inganda, hamwe n’igihembo c’ubumenyi bw’ibicuruzwa vy’intara ya jiangsu. Mu mwaka w’2018, iyo sosiyete yararonse icemezo c’ubuhinga bwo gukora imodoka TS16949 n’icemezo c’ubuhinga bwo gukora ibidukikije ISO14000.
Iyo sosiyete ifata "iterambere ry'ubuhinga n'ubuhinga, iterambere ridahera, ubuhinga bushasha, kwubaka ikimenyetso ca mbere-c'ibikoresho vy'ubuhinga bwa none vyo mu gihugu no guhaza abakiriya" nk'ubuhinga bwayo bwo guteza imbere. Ivyiyumviro bibiri vyashizeho ibisata bine: RF connector n'ikoraniro ry'intsinga igisata co gukora, umugwi coaxial umuravyo gufata, zinc alloy die casting umugwi, zinc alloy die casting, igice c'ibihimba bitagira ubushobozi n'ugukorana na kaminuza ya Nanjing mu bumanuko bushira ubuseruko, kaminuza ya jiangsu ihuriza hamwe ibikorwa, inyigisho n'ubushakashatsi electronic RFda "tongda" ibiro vy'ubutunzi bw'ubwenge" ibice bibiri binini.
Iryo shirahamwe rifise imyaka irenga 20 y’ubumenyi mu bijanye n’uguhingura, inguvu zikomeye z’ubuhinga, ikigo co gutunganya ibintu gihagaze c’umuvukanyi w’Umuyapani, imashini yo gucapura ihagaze ya zhongfeng, imashini yo gucapura ihagaze y’ubuhinga bwa none n’ibindi bikoresho biteye imbere hafi 100. igikoresho co kugerageza, igikoresho co kugerageza uburebure bwa filime y'Ubudage Fischer, ikigereranyo c'ingero zitatu- n’ibindi bikoresho vyo kugerageza hamwe n’ubushuhe bwinshi, buke, igihu c’umunyu, ukunyiganyiga n’ibindi bikoresho vyo kugerageza ukwizigirwa.
Kuva mu mwaka w’2009, iyo sosiyete yararonse uburenganzira 58 bwo mu gihugu mu bijanye n’ivyuma bifatanya, muri ivyo harimwo uburenganzira 18 bwo guhingura ibintu. Igikoresho nyamukuru gifatanya ibintu gifise urutonde rurenga 30, ubwoko 2000.

Iryo shirahamwe ryabaye inganda y’itumanaho ifasha ibikoresho vya zte, datang, putian, mobi, abashinwa, Hitachi na foxconn, kandi ryashinzwe nk’umucuruzi afise ubushobozi bwo gutanga ibikoresho vyo mu rwego rwa A.
Tongda izoharanira isoko kandi iteze imbere isoko n’uburyo bwiza cane, gutanga vuba, igiciro gisanzwe n’igikorwa ca mbere-inyuma y’ugucuruza. Turaha ikaze n’igishika abakiriya bo mu gihugu no mu mahanga kugira ngo baze gusura iyo sosiyete, ubuyobozi. Rondera iterambere rusangi kandi mureme kazoza keza hamwe.
