隨著PCB和NAND快閃記憶體等電子元件變得越來越緊湊和精細,焊點也越來越小。然而,較小的焊點更容易受到熱膨脹和收縮或外力的影響,這些外力可能會導致PCB彎曲,因此更容易剝離並失去導電性。
側面填充技術(Side Fill)
威剛為所有工業級固態硬碟提供側面填充技術,可有效減緩焊接點的壓力,讓關鍵元件與底層印刷電路板(PCB)接合得更加穩固,使得壓力均勻釋放於組件及PCB表面,從而防止PCB彎曲。確保工業設備在高振動額極端環境溫度的變化下,實現最佳的運行狀態,延長固態硬碟的使用壽命。

側面填充流程
為控制器的四角填充紫外線光固化樹脂,預留部分空隙,作為熱脹冷縮的緩衝,再用UV光固化四周,可有效強化控制器與PCB的結合。
