PCB Rework

“A key ingredient that is critical to the solder paste formulation is rosin, which plays a significant role in enhancing the performance of the solder paste and hence providing high process

Folks, Peter writes: Dear Dr. Ron, I amthrilled with your Excel® program to calculate IMC thickness as a function of time. However, I wanted to calculate IMC thickness for times not listed in the

Interconnect reliability is critical to the reliability of semiconductor packaging and electronic systems. If we look at the life cycle from the chip to the system—from IC design, wafer fab,

Folks, Let’s look in on Ivy University Professor Patty Coleman as she chats with John Archer about Walter Isaacson’s biography of Elon Musk. “I have to admit, reading about

Folks, This post is an excerpt fromIndium Corporation's The Printed Circuits Assemblers Guide to Solder Defects. Introduction Printed circuit board (PCB) issues can be a challenge, but not all of

Folks, Solder paste is arguably one of the most highly engineered materials. What is usually called solder paste “flux” is a combination of activators that dissolve oxides off metal

Folks, In my last post, I shared about an Excel®-based software toolcalled Line Balancer™to help candidates for SMTA Certification prepare for the line balancing part of the program. They

Reflow oven profiling can be a slow, costly and painstaking endeavor.Reflow profiles using thermal couples (TCs) can be asusefulasion-chromotography (IC) and strain gauge (SG) testing.However, the

Folks, When comparing the volume of solder paste provided by a circular versus square aperture, consider that if the side of the square is D and the diameter of the circle is also D, the square has
