PCBA Welding processing ngokuvamile inezidingo eziningi PCB board, okumele ukuhlangabezana nezidingo Welding. Ngakho kungani inqubo yokushisela idinga izidingo eziningi kangaka zamabhodi wesifunda? Amaqiniso afakazele ukuthi kuzoba nezinqubo eziningi ezikhethekile ohlelweni lwe-PCBA welding, futhi ukusetshenziswa kwezinqubo ezikhethekile kuzoletha izidingo ku-PCB.

Uma ibhodi le-PCB linezinkinga, lizokwandisa ubunzima benqubo yokufaka i-PCBA, futhi ekugcineni lingase liholele ekushiseni amaphutha, amabhodi angafaneleki, njll. Ngakho-ke, ukuze kuqinisekiswe ukuphothulwa kahle kwezinqubo ezikhethekile futhi kube lula ukucutshungulwa kwe-PCBA Welding, ibhodi le-PCB. kufanele ihlangabezane nezidingo zokwenziwa ngokosayizi nebanga lephedi.

Okulandelayo, ngizokwethula izidingo ze-PCBA welding processing ebhodini le-PCB.
Izidingo PCBA Welding processing ebhodini PCB
1.usayizi PCB
Ububanzi be-PCB (kuhlanganise nonqenqema lwebhodi lesifunda) kufanele bube bukhulu kuno-50mm futhi bube ngaphansi kuka-460mm, futhi ubude be-PCB (kuhlanganise nonqenqema lwebhodi lesifunda) kufanele bube bukhulu kuno-50mm. Uma usayizi mncane kakhulu, udinga ukwenziwa ngamaphaneli.
2. Ububanzi bonqenqema be-PCB
Ububanzi bonqenqema lwepuleti > 5mm, isikhala sepuleti esingu-< 8mm, ibanga phakathi kwe-base plate ne-plate edge > 5mm.
3. PCB ukugoba
Ukugobela phezulu: < 1.2mm, ukugobela phansi: <0.5mm, ukuguqulwa kwe-PCB: ubude bokuguqulwa okuphezulu ÷ ubude be-diagonal <0.25.
4. PCB mark point
Maka umumo: indilinga ejwayelekile, isikwele kanye nonxantathu;
Usayizi Maka: 0.8 ~ 1.5mm;
Izinto zokumaka: ucwecwe lwegolide, i-tin plating, ithusi neplatinamu;
Izidingo zobuso bukaMark: indawo engaphezulu iyisicaba, ibushelelezi, ayinayo i-oxidation nokungcola;
Izidingo ezizungeze umaki: akumele kube nezithiyo ezifana namafutha aluhlaza okusobala ukuthi ahlukile kumbala wophawu ngaphakathi kwe-1mm nxazonke;
Maka indawo: ngaphezu kuka-3mm ukusuka onqenqemeni lwepuleti, futhi akumele kube khona imbobo, indawo yokuhlola namanye amamaki phakathi kuka-5mm.
5. PCB pad
Azikho izimbobo kumaphedi wezingxenye ze-SMD. Uma kunembobo edlulayo, i-solder paste izogeleza ingene embobeni, okuholela ekuncipheni kwethini kudivayisi, noma ithini ligeleze liye kolunye uhlangothi, okuholela ebhodini elingalingani futhi lingakwazi ukuphrinta unamathisele we-solder.

Ekwakhiweni nasekukhiqizeni kwe-PCB, kuyadingeka ukuqonda olunye ulwazi lwenqubo yokushisela ye-PCB ukuze wenze imikhiqizo ifanele ukukhiqizwa. Okokuqala, ukuqonda izidingo zesikhungo sokucubungula kungenza inqubo yokukhiqiza elandelayo ibe bushelelezi futhi kugweme izinkinga ezingadingekile.
Okungenhla yisingeniso sezidingo ze-PCBA welding processing kumabhodi we-PCB. Ngethemba ukuthi ingakusiza futhi ufune ukwazi okwengeziwe nge-PCBA welding processing information.
