Ubhedu olushinyeneyo lubonelela ngezakhono eziphezulu zokuthwala zangoku kodwa lukwanciphisa nokuguquguquka kwePCB. Ulungelelwaniso olufanelekileyo kufuneka lwenziwe phakathi kwezi zinto ukuze kuphunyezwe ukusebenza ngokupheleleyo.

2. Amacandelo aphambili okwenziwa kwe-PCB eguquguqukayo:

A. Imaski ye-solder ye-PCB eguquguqukayo: Imaski ye-solder ngumaleko okhuselayo ogqume imikhondo yobhedu engenanto kwi-PCB. Inceda ukuthintela iibhulorho ze-solder, ukubola, kunye neebhulukhwe zombane ngexesha le-welding. I-PCB eguquguqukayo isebenzisa imathiriyeli yemaski ekhethekileyo ye-solder ukuqinisekisa ukuguquguquka kunye nokuqina. Ukhetho lwemaski ye-solder ye-PCB eguquguqukayo kunye nenkqubo yesicelo ifuna ukuqwalaselwa ngononophelo kuyilo lwePCB kunye nokusetyenziswa kwayo.

B. I-Plexible PCB Layout: Uyilo lwePCB oluyilwe kakuhle, oluguquguqukayo lubaluleke kakhulu ekusebenzeni kakuhle kunye nokuthembeka. Ibandakanya ukubekwa kwamacandelo, ukuhanjiswa kwendlela yokulandela umkhondo, kunye nokuqwalaselwa kwemfezeko yomqondiso. Amacandelo kufuneka abekwe ngendlela evumela ukuba i-PCB igobe kwaye igobe ngokufanelekileyo. Umkhondo kufuneka uhanjiswe ukunciphisa uxinzelelo kwiindawo eziguquguqukayo kunye nokuqinisekisa ukuhanjiswa komqondiso osebenzayo. Iindlela ezigqwesileyo zokuyila uyilo lwePCB olubhetyebhetye lubandakanya ukusebenzisa imikhondo egobileyo, ukuphepha ii-engile ezibukhali, kunye nokuqinisekisa ucoceko olwaneleyo phakathi kweetrayisi.

C. Flexible PCB ancamathelise sheet: An sheet encamathelayo isetyenziswa kwimveliso PCB bhetyebhetye ukuba ibhondi umaleko ezahlukeneyo kunye. Inika amandla omatshini, ukuzinza, kunye nokugquma. Kukho iintlobo ezahlukeneyo zamaphepha ancamathelayo akhoyo, njengamaphepha asekelwe kwi-acrylic, amaphepha asekelwe kwi-epoxy, kunye namaphepha asekelwe kwirabha. Ukukhethwa kwephepha lokunamathela kuxhomekeke kwizinto ezifana nokumelana nobushushu, iimfuno zokuguquguquka, kunye nokuhambelana nezinye izinto. Ukukhetha iphepha lokuncamathelisa elifanelekileyo kubaluleke kakhulu ukuqinisekisa ukuthembeka kunye nokuqina kwePCB yakho ebhetyebhetye.
