	*671-9408078 => Thailand Factory 71 - April 1989 (it's a 6128)		*671-9408078 => Thailand Factory 71 - April 1989 (it's a 6128)

		+
		+	=PCB Markings=
		+	There are some markings on some boards that denote the materials used to build the board or adherence to certain standards.
		+
		+	==UL94 Flammability testing standard==
		+	The standard determines the material’s tendency to either extinguish or spread the flame once the specimen has been ignited.
		+
		+	Classifications from lowest (Least flame-retardant) to highest (Most flame-retardant):
		+
		+	* HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm
		+	* V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
		+	* V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
		+	* V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
		+	* 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
		+	* 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole.
		+
		+	So, a board with a 94V-0 marking is supposed to stop burning after 10 seconds and may drip non-inflamed particles.
		+
		+	Please visit the [https://en.wikipedia.org/wiki/UL_94 Wikipedia page] on the UL94 standard for more information.
		+
		+	==NEMA grade designations==
		+	[https://www.nema.org NEMA (National Electrical Manufacturers Association)] is the largest trade association of electrical equipment manufacturers in the United States, and publishes standards for electrical products.
		+
		+	One of these standards is the Insulating Material Standard, which includes designation for flame retardant materials (FR), like the ones the PCBs are made of.
		+
		+	Examples of NEMA designations include the following:
		+	* FR-2 : Synthetic resin bonded paper. ([https://en.wikipedia.org/wiki/FR-2 Wikipedia FR-2])
		+	* FR-4 : Glass-reinforced epoxy laminate material, typically employing bromine as flame retardant. ([https://en.wikipedia.org/wiki/FR-4 Wikipedia FR-4])
		+
		+	For information on the different substrates used in PCB manufacturing, please check this [https://en.wikipedia.org/wiki/Printed_circuit_board#Common_substrates Wikipedia page].
		+
		+	==Material codes==
		+	There are other codes referring also to materials and their properties, please check the table below:
		+
		+	[[File:UL_Material_Standards.png\|600px]]
		+
		+	==Other markings==
		+	There are some boards which have some combinations of letters and numbers surrounded by white dot patterns:
		+
		+	[[File:PCB_White_Dot_Marking.png]]
		+
		+	These may be production line identification markings for quality control.
