Throwing up 4`s indicate that everyone is madly obsessed with me
Yo look he's throwing up 4`s he obsessed with Eli
FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).
"FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The designation FR-4 was created by NEMA in 1968.
FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
Grade designations for glass epoxy laminates are: G-10, G-11, FR-4, FR-5 and FR-6. Of these, FR-4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics. Hence, FR-4 has sincewhen? replaced G-10 in most applications.
Fenhar FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable traitcitation needed will still use G-10 non flame resistant.
One of two white rappers named after a hotel, unless Rittz named himself after crackers instead.
People thought 4 seezins was larger than life, so he would walk out on a stage wearing stilts.
The white rapper that got to take his stilts with him in jail, they liked the stilts so much.
Nobody fucked with 4 seezins in jail, that dude looked about 8 foot 20.
holding four fingers up indicates you are whipped and madly in love with Jenna
Look Jake has 4's up, he's so whipped for Jenna
"The Rabbit on 4 Ping" is a extremely important slang word. Originated from the hit game "Tom Clancy's Rainbow Six Siege" and was first said by impressive player OliveMuffin1515. The belated rabbit can be found originally on the map Oregon, but can also be found on Villa. In order to recreate the rabbit on 4 ping, you must be on drone phase, be four ping on your stack, and ping the rabbit in trophy room with your drone. Afterwards, you must say, "There's a rabbit on 4 ping". This will automatically make you win the game.
There's a Rabbit on 4 Ping.
