Kuyilo PCB, uhlobo umngxuma zinokwahlulwa ibe imingxunya eyimfama, imingxuma engcwatywayo kunye nemingxunya disc, ngamnye ube iimeko ezahlukeneyo isicelo kunye neengenelo, imingxuma imfama kunye nemingxuma engcwatywe zisetyenziswa ikakhulu ukuphumeza uqhagamshelo lombane phakathi iibhodi multi-layer, kunye disc imingxuma zilungisiwe kunye amacandelo welding. Ukuba imingxuma eyimfama kwaye engcwatywe zenziwe kwibhodi ye-PCB, ngaba kuyimfuneko ukwenza imingxuma yediski?
- Yintoni ukusetyenziswa kwemingxuma eyimfama kunye nemingxuma efihliweyo?
Umngxuma oyimfama ngumngxuma odibanisa umaleko womphezulu ukuya kumaleko angaphakathi kodwa ungangeni kuyo yonke ibhodi, ngelixa umngxuma ongcwatyiweyo ngumgodi odibanisa umaleko wangaphakathi kwaye awubonakali kuluhlu lwangaphezulu. Ezi zimbini zidlulayo zisetyenziselwa ukuqaphela uxhulumaniso lombane phakathi kweebhodi ze-multi-layer kunye nokuphucula ukudibanisa kunye nokuthembeka kwebhodi yesiphaluka. Banokunciphisa ukuwela imigca phakathi kweebhodi zebhodi kunye nokunciphisa ubunzima bocingo, ngaloo ndlela kuphuculwe ukusebenza ngokubanzi kwe-PCB.
- Yintoni ukusetyenziswa komngxuma wepleyiti?
Imingxunya yediskhi, eyaziwa ngokuba yimingxuma yokutyhutyha okanye imingxunya, yimingxunya ebaleka ukusuka kwelinye icala lePCB ukuya kwelinye. Isetyenziselwa ikakhulu ukulungiswa kunye ne-welding yamacandelo, kunye nokuqonda ukuxhamla kombane phakathi kwebhodi yesiphaluka kunye nezixhobo zangaphandle.
Umngxuma we-disc uvumela i-solder wire okanye i-pin ukuba idlule kwi-PCB ukwenza uxhulumaniso lombane kunye ne-solder pad kwelinye icala, ngaloo ndlela ukugqiba ukufakwa kwecandelo kunye nokudibanisa kwesekethe.
- Unokukhetha njani imingxuma eyimfama / engcwatywe kunye nemingxuma ye-PAD?
Nangona imingxuma eyimfama kunye nemingxuma engcwatywayo inokufezekisa uxhulumaniso lombane phakathi kweebhodi ze-multi-layer, azikwazi ukuthatha indawo ngokupheleleyo indima ye-disc.
Okokuqala, umgodi we-disc unenzuzo ekhethekileyo yokulungiswa kwecandelo kunye ne-welding, enokuqinisekisa ukuzinza nokuthembeka kwamacandelo.
Okwesibini, kwezinye iisekethe ezifuna ukuqhagamshelwa kwizixhobo zangaphandle, imingxuma yediski iyimfuneko.
Ukongezelela, kwezinye iisekethe eziyinkimbinkimbi, imingxuma eyimfama, imingxuma efihliweyo, kunye nemigodi ye-disc ingadinga ukusetyenziswa ngaxeshanye ukuhlangabezana neemfuno ezahlukeneyo zokudibanisa.
