Metall folga - bu metall kengaytmadan yasalgan nozik metall qatlam bo'lib, har bir turdagi ultra yupqa metall folga turli sohalarda turli xil va muhim ilovalarga ega. Masalan, po'lat va qotishma plyonkalar asosan elektronika va aerokosmosda qo'llaniladi, titanium qotishma plyonkalar reaktiv dvigatelning yonish quvurlarida dekorativ panjara qilish uchun ishlatilishi mumkin, volfram va molibden plyonkalari elektron quvurlar va issiqlik hosil qiluvchi elementlar uchun, temir-nikel yumshoq- magnit qotishma plyonkalar miniatyuradagi yuqori chastotali impuls transformatorlari, magnit magnitafonlar va boshqalarning yadrolarini, shuningdek, mis qoplamali laminatlarni tayyorlash uchun ishlatilishi mumkin bo'lgan keyingi bo'limda eslatib o'tiladigan mis plyonkalarni tayyorlash uchun ishlatiladi.
Mis bilan qoplangan laminat (CCL) - elektron shisha tolali mato yoki qatron bilan singdirilgan boshqa mustahkamlovchi materiallar, bir tomoni yoki ikkala tomoni mis folga bilan qoplangan va plastinka materialiga issiq presslangan, mis bilan qoplangan taxta deb ataladi, turli xil bosilgan elektron plataning shakllari va funktsiyalari har xil turdagi bosma sxemalardan tayyorlangan mis qoplamali taxtada o'yilgan, burg'ulash teshiklari va boshqa jarayonlar.
Bosilgan elektron platadagi mis folga o'zaro bog'lanish o'tkazuvchanligi, qo'llab-quvvatlash va boshqalar rolini o'ynaydi, bosilgan elektron plataning ishlashi plataning sifati bilan bevosita bog'liqdir, uning ahamiyati o'z-o'zidan ravshandir va uning narxi va qiyinligi. mis folga ishlab chiqarish yuqori, shuning uchun ishlab chiqaruvchilar uchun ishlab chiqarish tannarxini pasaytirish uchun mis folga foydalanish tezligini oshirish uchun mis folga kesishda yuqori aniqlik talab qilinadi.
Lazerli kesish bilan solishtirganda, an'anaviy pichoqni kesish jarayoni samaradorlik, ishlov berish tezligi, kesish yo'qotilishi va kesish aniqligi jihatidan biroz pastroq. Hozirgi vaqtda UV lazerlari sanoatda mis folga kesish uchun keng qo'llaniladi. Nuffy Optoelektronika tomonidan ishlab chiqilgan sanoat darajasidagi nanosoniyali qattiq holatdagi lazer yuqori nur sifati va yuqori quvvatga ega 355nm UV lazerini olib keladi, bu ayniqsa optikani, harakatlanuvchi qismlarni va ko'rishni boshqarish dasturini birlashtirgandan so'ng mis folga kesish uchun mos keladi.
U yuqori nurlanish sifatiga ega (M2<1.2), the focusing focal point obtained after joining the supporting optical equipment is very small, the spot diameter is micrometer, the power density is very high, and the parameters such as the position, size, and focal depth of the focal point can be set to perform high-quality cutting with a small cutting gap and high precision. Moreover, UV laser wavelength is short, material applicability is wide, absorption rate is high, the cutting process is "cold processing", with very small pulse width (<25ns), bringing non-thermal damage to the material, there is no heating or thermal deformation on the inner layer of the processed surface and the nearby areas, the heat-affected zone is small, and there is no carbonization and burring on the edge of the cut copper foil, the effect is very good, the cutting gap is small, and the precision is high. , burr, the effect is very good, can ultraviolet processing basically become synonymous with precision cold processing. At the same time the efficiency of laser processing is also very high, can be good and fast for manufacturers to bring real benefits.
Aloqa sanoatining jadal rivojlanishi bilan mis qoplamali laminatlar misli ko'rilmagan katta bozorni olib keldi va mis qoplamali laminatlar uchun asosiy material sifatida mis folga ilovalariga talab o'sishda davom etadi. Nuffildning sanoat darajasidagi nanosekundli qattiq holatdagi lazerlari yuqori aniqlikdagi va yuqori zichlikdagi kesishni, shuningdek, mikrovia bilan ishlov berishni amalga oshirishi mumkin, bu mis folga kesish uchun ideal ishlov berish vositasidir, chunki u mis qoplamali laminatlarning hozirgi rivojlanish sur'atlariga javob beradi.
