Zvishandiso zveSolder Balls

Bhora Grid Array (BGA) Packaging

BGA inoramba iri imwe yeakanyanya kupararira mashandisirwo emabhora e solder. Kuenzaniswa neyechinyakare Dual In-line Package (Fabrika) kana mapakeji akafuratira, BGAs inopa yakakwira yekubatanidza density uye yepamusoro yemagetsi kuita. Yepamberi BGA tekinoroji ikozvino inotsigira zviuru zveanotengesera bhora kubatanidza, kusangana nezvido mu-high-performance computing uye 5G. kutaurirana fields. The ultra-fine BGA assembly requirements also depend on land geometry, paste transfer and placement control, so ball size should not be evaluated independently of the complete process.

3D Integrated Circuits

Sezvo Mutemo waMoore uchiswedera kumiganhu yemuviri, 3D akasanganiswa maseketi anomiririra tekinoroji yekubudirira. Mabhora eSolder anoita basa rakakosha mune ino dura, achigonesa kubatanidzwa kwepamusoro uye kuita kuburikidza neakamira stacking uye kubatanidza akawanda akaturikidzana emachipisi.

Micro-Electro-Mechanical Systems (MEMS)

Mumidziyo yeMEMS, mabhora madiki ekutengesa anofambisa chaiyo mechanic uye magetsi ekubatanidza, achitsigira akasiyana sensor uye actuator mashandiro.

Solder Bhora Diameter Sarudzo

Kusarudza iyo chaiyo solder bhora dhayamita chinhu chakakosha mukusangana kwePCB, inokanganisa zvakananga mashandiro emagetsi, simba remagetsi, uye kuvimbika kwemajoini ekutengesa. Mainjiniya anofanirwa kutarisisa zvinhu zvakawanda kuti ave nechokwadi chemhedzisiro.

Zvinhu Zvinokurudzira Solder Bhora Diameter Sarudzo
