Godka A toobinta oo waa la gooyay in ay u oggolaadaan fur madaxa guri in la isticmaalo waxaa loo yaqaanaa god countersink. Waxa kale oo la odhan karaa sida god toobinta oo la jarjar laminate PCB ah, ama god abuuray oo isticmaalaya daloolin a. Ujeedada ugu weyn waa in aynu madaxa fur a countersunk, marka la geliyo iyo xiri hoos ku godka, si ay u fadhiisan radi dusha sare ee laminate ah. Koorta qaabeeya godka, oo waa la gooyay galay laminate PCB ah, waa countersink ah. Waxaa guud ahaan waxaa loo isticmaalaa in la oggalaado madaxa tapered of fur si ay u fadhiisan radi sare ama hoose ee laminate ah.

Waxaa inta badan loo isticmaalo, si fur madaxa guri fariisan karo radi dusha si aad u eegto nadiif ah iyo rakibidda. Si loo xaqiijiyo in design saxda ah ee wax soo saarka, soo saarayaasha ugu baahan yihiin faahfaahinta dhexroor godka. Waxa kale oo ay u baahan tahay in la ogaado haddii godka la plated ama ma. Ogaanshaha haddii godka waa saxan ama ma aha muhiim, sababtoo ah xaaladaha qaar ka mid ah meel daloosha oo unplated laga yaabaa in lagu xeeldheer in qaab dhismeedka, oo wuxuu keeni karaa dhibaatooyin u baahan in la saxo lahaa dahaadhay. Countersinks caadi ahaan 82 degree ama xagal 90 digrii, Si kastaba ha ahaatee, xaglo kale waa suurto gal ah in qofka macaamiisha ah u baahan tahay si ay u siiyaan in ay fabricatorandacoonayeen PCB ah.

Waayo, qodista sax ah oo godad countersink, macluumaadka soo socda waxaa loo baahan yahay:

▪ Waa kuwee dhinac ee guddiga waa godka countersink waa in la qoday, on top ama hoose?

▪ Ma ka saxanka iyo usheeda dhexe in uu noqdo iyada oo plated ama non-plated?

▪ xagal gabogabaysmo ama xagal countersink

▪ dhexroor Countersink

▪ dhexroor The dhammeeyayna of usheeda dhexe ee godka

▪ Qotada countersink waa in la qoday

Hoos waxaa ku sawir ah kaas oo bixiya tusaale ka mid ah god countersink:

A: xagal Countersink, D: Countersink Ballaca, d: dhexroor Hole, H: qoto dheer Hole
