Ibhulorho Welding:

Ibhulorho ye-solder kukudibana ngombane ngengozi phakathi kwabaqhubi okungafunekiyo ngenxa yeqhekeza elincinci le-solder. Ziyaziwa ngokuba “ziisekethi ezimfutshane” kwi PCB isigama. Kunzima ukufumanisa iibhlorho ezidityanisiweyo xa kukho izinto ezishiyekileyo. Ukuba ayisombululwanga, inokubangela ukonakala kwamanye amacandelo kunye neebhodi zesekethe. Isigqumathelo se-welding (okt, umaleko omncinci wepolymer usetyenziswa kwimizila yobhedu kwibhodi yesekethe eprintiweyo ukuyikhusela kwi-oxidation kwaye kuthintele ukuyilwa kwebhulorho phakathi kweepads. Esi sigqumathelo se-welding siyimfuneko kwimveliso ye-PCBS, kodwa ayiloncedo kangako kwimeko yezinto ze-PCB ezenziwe ngesandla. Iibhodi zesekethe ukuba zithengiswe ngokuzenzekelayo, ibhafu ye-solder kunye neendlela zokuhlaziya ze-soldering zihamba phezulu. Ukuthintela ukuwelda iibhlorho ngexesha lendibano ye-PCB, okokuqala kufanelekile ukumisela uhlobo olufanelekileyo lwesigqumathelo se-welding ekufuneka sisetyenzisiwe ngexesha lendibano ye-PCB. Oku kunokuba kukuqwalaselwa okunobuzaza xa ufumana ubume bePCB efanelekileyo kunye nohlobo lwePCB yeprojekthi yakho.

Abavelisi bezixhobo zombane kufuneka baphande nzulu ngoncedo kunye nezinto ezingalunganga kuhlobo ngalunye lwefilimu ye-solder ngaphambi kokuthatha isigqibo sokuba bakhethe i-epoxy liquid, ifoto ye-liquid yeefoto (i-LPSM) okanye ifilimu eyomileyo yefoto ye-solder (DFSM). Banokunceda abenzi be-PCB babonisane kwaye bafune indibano efanelekileyo ye-PCB ngenkqubo ecacileyo yokuvelisa kunye ne-PCB. Kubo bonke abavelisi be-elektroniki, ukuthintela iibhlorho ezidityanisiweyo kunokubandakanya ukutyalomali okongeziweyo kwexesha kunye nemali, kodwa kunokukunceda ufezekise imbuyekezo ebalulekileyo yexesha elide.

Izizathu iwelding Bridge:

Unobangela oyintloko webhulorho ye-weld kukungalunganga kwePCB. Ubungakanani bephakheji yamacandelo ayo kunye nombono wokungonelanga kokusetyenziswa kwezinto ezidityanisiweyo ziye zanda ngenxa yesidingo sokwazisa ubuchwephesha obukhawulezayo kunye nokukhawuleza. Lo ngumceli mngeni omkhulu kwii-oems, ezifuna ubume bePCB ngokugqibeleleyo nangokufanelekileyo. Bahlala bephela beyekisa kulwakhiwo lwe-PCB ukuze bazise iimveliso ezintsha kwintengiso.

Abanye oonobangela bokwenza ibhulorho kubandakanya ukungabikho kokuxhathisa kwe-welding phakathi kweepads kwibhodi yesekethe.Umaleko ongonelanga wepolymer kwimigca ye-COPPER yokulandela umkhondo we-PCB, edla ngokubizwa ngokuba yi-weld mask, nayo ibangela iingxaki nge-bridge ye-weld. Xa isithuba sezixhobo siyi-0.5mm okanye ngaphantsi, umda wokucoca indawo engafanelekanga inokuba sisizathu sebhulorho. Ukuchazwa kwetemplate ngokungachanekanga kungakhokelela ekunciphiseni i-solder paste, enokuthi ikhokelele kwiiBhulorho. Ngenxa yokutywinwa okungafanelekanga phakathi kwePBB kunye neplate ye-solder, ubukhulu beetemplate, iimpazamo ekubekweni kwezinto eziphezulu zeentaba okanye xa kuthelekiswa ne-PCB, ukubhaliswa kwe-solder engafanelekanga, ukuhanjiswa okungalinganiyo kwe-solder paste, ezi ziingxaki eziqhelekileyo ezikhokelela kwibhulorho ye-solder ngexesha le-PCB indibano.

Amanyathelo othintelo:

Qinisekisa ukuba ucingo ngalunye lugqunywe kukumelana nokubhobhoza phakathi kwabo kwaye alunakusebenziseka ngenxa yokunyamezelana okungqongqo, emva koko ichaze utshintsho olwenziweyo malunga nelo candelo. Ithempleyithi ye-welding ecetyiswayo eyi-0.127 mm eshinyeneyo, itemplate yentsimbi engenasici kunye nokusika kwelaser nayo ikulungele ukushiywa kwesithuba kwe-0.5 mm. Ezi zizikhuselo zokuphepha iibhlorho ezine-welding kwaye ufumane isisombululo sendibano ye-PCB efanelekileyo.
