What are C4 bumps?
Flip chip, also known as controlled collapse chip connection or its abbreviation, C4, is a method for interconnecting dies such as semiconductor devices, IC chips, integrated passive devices and microelectromechanical systems (MEMS), to external circuitry with solder bumps that have been deposited onto the chip pads.
What does bumping mean in chemistry?
Bumping is a phenomenon in chemistry where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container.
What does bump mean on a forum?
“To bump a thread on an Internet forum is to post a reply to it purely in order to raise the thread’s profile.”
What is Microbump?
Micro-bump consists of down sized Cu pillar and solder is the chosen interconnect technology for die stacking volume manufacturing. The interconnect solder bump height is shortened to less than 20µm due to significantly reduced Cu pillar diameter.
Why is bumping hazardous?
Bumping can splash hot material out of a flask: onto your hand or onto a hotplate surface where it might start a fire. Bumping is hazardous, not to mention frightening when a bubble unexpectedly erupts. Several methods can be used to prevent bumping and ensure smooth boiling.
What is bumping a post on Facebook?
This is a common occurrence in posts in groups, especially when a group is updating the rules or guidelines for the community.
