倒裝晶片或BGA下方焊點的形狀是由合金的表面張力、所使用助焊劑的活性、回流期間元件上的張力或壓縮以及阻焊層開口尺寸所控制。如果阻焊層的開口太小，焊點的濕潤就會被限制在焊盤的一小部分區域內。如果阻焊層的開口太大，則無法阻止焊料濕潤到焊盤旁邊的跡線上。
Robotic soldering has evolved from a productivity upgrade into a precision requirement—especially as electronics become smaller, denser, and require shorter production cycles. In Part 1 of this
Silver prices are escalating rapidly, consistently trending upward. If you manage a bill of materials (BOM) for electronics manufacturing, you understand precisely how this volatility impacts your
Manufacturing modern electronics often feels like a balancing act—literally. Assembly tilt and uneven coplanarity are persistent headaches that compromise solder joints, leading to weak connections
