Kukho amacandelo amaninzi e-elektroniki achanekileyo kwiibhodi zendibano zePCB, kwaye amacandelo amaninzi abuthathaka kumbane.Ukothuka okuphezulu kunombane olinganisiweyo kuya kuwonakalisa la malungu.Nangona kunjalo, i-PCBA yonakaliswe ngumbane ongatshintshiyo kunzima ukuphanda inyathelo ngenyathelo ngexesha lovavanyo olusebenzayo.Yintoni ebulalayo ngakumbi kukuba ezinye iibhodi ze-PCBA zisebenza ngesiqhelo ngexesha lovavanyo, kodwa xa imveliso egqityiweyo isetyenziswa ngumthengi, iziphene ngamaxesha athile zivela, ezisa iingozi ezinkulu emva kokuthengisa kwaye zichaphazela uphawu lwenkampani kunye nokuthakazelelwa.Ke ngoko, kwinkqubo yokusetyenzwa kwePCB, kufuneka sincamathele ukubaluleka okukhulu kukhuseleko lwe-ESD.
PCBFuture icebisa ezi ndlela zilandelayo zokhuseleko ESD ngexesha PCBA:
1. Qinisekisa ukuba amaqondo obushushu kunye nokufuma kwe workshop kuphakathi komgangatho ophakathi, 22-28 degrees celcius, kunye nokufuma 40%-70%.
2. Bonke abaqeshwa mabakhuphe umbane ongatshintshiyo xa bengena naxa bephuma kumasifundisane.
3. Nxiba njengoko kufuneka, nxiba ikepusi yombane, impahla yombane, kunye nezihlangu zombane.
4. Zonke izitishi zokusebenzela ezifuna ukuchukumisa ibhodi yePCBA mazinxibe iringi yentambo engashukumiyo, kwaye ziqhagamshele iringi yentambo engashukumiyo kwialam engatshintshiyo.
5. I-static wire yahlulwe kwisixhobo somhlaba ucingo ukuthintela ukuvuza kwezixhobo kwaye kubangele umonakalo kwibhodi ye-PCBA.
6. Zonke iiracks ezimileyo zefreyim yezithuthi kufuneka ziqhagamshelwe kucingo olusezantsi olungatshintshiyo.
7. Yenza uhlolo lwe-ESD olungaguqukiyo ngokungqongqo ngokweemfuno zolawulo lomgangatho we-ISO.Umbane omileyo awubonakali kwaye awubonakali ngexesha lenkqubo yokuvelisa ibhodi yesekethe, kwaye ngokufuthi kubangela iingozi ezibulalayo kwiibhodi zesekethe zePCBA ngokungazi.Ngoko ke, PCBFuture icebisa ukuba umphathi ngamnye kufuneka anikele ingqalelo engqongqo kulawulo ESD static, ukuze inkqubo yokuvelisa PCBA inokulawulwa ngokupheleleyo.
