Uma kuqhathaniswa nebhodi lesifunda elinohlangothi olulodwa, ibhodi le-pcb elinamacala amabili linobuningi bezintambo eziphakeme nokuvula okuncane. , njengemfucumfucu yamabhulashi, umlotha wentaba-mlilo, njalonjalo, uma sekushiywe emgodini ngaphakathi, kuzokwenza ikhemikhali licwilise ithusi, lilahle i-electroplating yethusi.

Ukuze kuqinisekiswe ukusebenza okuthembekile kwebhodi yesifunda emaceleni amabili, umgodi wokuxhuma ebhodini kufanele ushiselwe ngohlobo lwentambo kuqala, futhi ingxenye yokungena yethiphu yocingo yokuxhuma kufanele inqunywe, ukuze ungagwinyi isandla se-opharetha. Lona umsebenzi wokulungiselela womugqa wokuxhuma webhodi.

Ngakho-ke, yiziphi izinkinga okufanele zinakwe ku-welding emaceleni e-pcb board?

1. Kumadivayisi adinga ukwakheka, kuzolandela izidingo zomdwebo wenqubo, ukubumba kuqala bese kuba yi-plug-in.

2. Ngemuva kokubunjwa, uhlobo lwe-diode kufanele lubheke phezulu, futhi ubude bezikhonkwane ezimbili akufanele buhambisane.

3. Kumadivayisi anezidingo zobumbano, kuzokwazi ukuthi ubumbano ngeke bufakwe kolunye uhlangothi. Akukho ukuthambeka okusobala okuzovunyelwa amadivayisi amile noma avundlile ngemuva kokufakwa.

4. Amandla wensimbi kagesi oku-soldering angama-25 ~ 40W, izinga lokushisa lekhanda le-iron soldering kufanele lilawulwe ngo-242 ℃ noma kunjalo, futhi isikhathi sokushisela kufanele silawulwe ngemizuzwana emi-3 ~ 4.

I-5, i-welding ngokuvamile ngokuya ngedivayisi kusuka phezulu kuya phezulu, ukusuka ngaphakathi kuya ngaphandle kwesimiso se-welding ukuze isebenze, isikhathi se-welding sokufunda, isikhathi eside kakhulu kuzoba yidivayisi eshisayo, kuzophinde futhi kushise ucingo lwentambo egqoke ipuleti egqoke ithusi .

6, ngoba iwelding emaceleni amabili, ngakho-ke kufanele futhi yenze uhlaka lwenqubo ukubeka ibhodi lesifunda, inhloso akuyona ukucindezela idivayisi engezansi.

7. Ngemuva kokuphothulwa kokushisela, kuzokwenziwa ukuhlolwa okuphelele ukubheka izindawo lapho kukhona khona ukufakwa kokuvuza kanye nezinsimbi. Ngemuva kokuqinisekisa, nquma izikhonkwane zedivayisi ezingasasebenzi bese uzivumela zingene kwinqubo elandelayo.

8. Umsebenzi othile uzolandela ngokuqinile amazinga wenqubo efanele ukuqinisekisa ikhwalithi yokushisela.

Lokhu okungenhla kuyizinyathelo zokuphepha zokushisela kwebhodi le-pcb elinamacala amabili. Uma ungazi, ungaxhumana nomakhi webhodi le-China pcb - Inkampani yaseYongmingsheng Circuit board nganoma yisiphi isikhathi.
