Miyezo Yoyendera Bungwe Lozungulira
1. Kuchulukaku ndikoyenera kuyang'anira ukubwera kwa mafoni a HDI ma board board.
2. Dongosolo lachitsanzo lidzawunikidwa molingana ndi GB2828.1-2003, general inspection level II.
3. Kuyang'ana kumachokera kuzinthu zopangira luso komanso zitsanzo zoyendera.
4. Mulingo waubwino woyenerera umachokera ku mtengo wa AQL: Kalasi A = 0.01, Kalasi B = 0.65, Kalasi C = 2.5.
5. Zida zoyesera ndi zida: pulagi gauge, vernier caliper, reflow uvuni, dynamometer, maginifying galasi, digito multimeter, kutentha kosalekeza ndi chinyezi bokosi, kiyi moyo tester, golide-yokutidwa wosanjikiza makulidwe tester, lathyathyathya nsangalabwi kapena galasi, kutchinjiriza kukana tester , kutentha kosalekeza kwa ferrochrome.
6. Gulu lachilema: serial number Kuwunika Kufotokozera kwa cholakwika Choyika chakunja ndi chonyowa, zida zimayikidwa m'gulu la zolakwika Gulu la CB Ndemanga 1 Palibe chizindikiro mkati kapena kunja kwa phukusi, chizindikiro cholakwika, kudontha kwamadzi mkati, palibe mikanda yoteteza chinyezi, palibe khadi la chinyezi. , zipangizo zosakanikirana, palibe Phukusi la vacuum.

2. Zinthu zoyendera zomwe zili mu lipoti lotumiza la wopanga sizikugwirizana komanso zimakwanira molingana ndi zomwe tikufuna pakuwunika, zoyeserera sizikukwaniritsa zofunikira, lipotilo lilibe kuvomerezedwa ndi woyang'anira wabwino kapena ogwira ntchito zapamwamba, ndi lipotilo. zomwe zili ndi zabodza, ndi zina. Ngati zomwe zili pamwambazi sizikukwaniritsidwa.B zowunikira manambala azinthu Kufotokozera kwachilema Zambiri Zomwe zikubwera ndizosiyana ndi wopanga zitsanzo, nambala ya mbale yosiyana, mbale zosiyanasiyana (kuphatikiza palibe chizindikiritso cha mbale), palibe kuzungulira kopanga, komanso palibe muyezo wafakitale.Sipayenera kukhala mbali zakuthwa kuzungulira PCB kuti zikhudze gulu ndikuvulaza wogwiritsa ntchito.Porous ndi ochepa pores Pores zazikulu ndi zazing'ono (malinga ndi zofunikira za zojambula zojambula) Pali mkuwa wotsalira mu dzenje la NPTH, ndipo pali okosijeni mu dzenje.) pobowo yomalizidwa: ngati ipitilira zomwe zili pansipa
3 Kubowola mabowo ozungulira: NPTH: +/-2mil (+/-0.05mm);NPTH: dzenje lamkuwa la B osamira;PTH: dzenje lamkuwa lomira PTH: +/- 3mil (+/-0.075mm) 2,
