What is OSP coating?
OSP is a water-based, organic surface finish that is typically used for copper pads. It selectively bonds to copper and protects the copper pad before soldering. OSP is environmentally friendly, provides a coplanar surface, is lead-free, and requires low equipment maintenance.
What is the purpose of OSP?
Open Settlement Protocol (OSP) is a client-server protocol that manages access control, accounting, usage data and inter-domain routing to make it easier for Internet service providers (ISPs) to support IP telephony. OSP facilitates information exchange through the Extensible Markup Language (EML).
What is OSP made of?
Organic solderability preservative or OSP is a method for coating of printed circuit boards. It uses a water-based organic compound that selectively bonds to copper and protects the copper until soldering. The compounds typically used are from the azole family such as benzotriazoles, imidazoles, benzimidazoles.
Is OSP conductive?
Is OSP Conductive? OSP is conductive. OSP coated PCBs also performs better when it comes to solder wetting when flux meets vias and pads.
What is ENIG finish PCB?
Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
What is Smobc in PCB?
– To provide a solderable surface when assembling (soldering) the components to. the PCB. Most surface finishes are considered SMOBC (Solder Mask Over Bare Copper).
What is OSP drafting?
Drafter, OSP Mentor and assist newer drafters. The Drafter, OSP creates project work prints based on designs put together by the designer. The Drafter, OSP would create drawings for the placement of fiber optic…
What is OSP in oil and gas?
Also known as: OSP. An official selling price is an announced price, typically for crude oil, that is offered to all buyers in the market for a set period of time (usually a calendar month).
What is Enepig?
ENEPIG is an acronym for Electroless Nickel Electroless Palladium Immersion Gold. This type of finish offers abundant benefits that make it suitable for a variety of applications.
What is the difference between ENIG and HASL?
HASL has a excellent solder-ability and has a good shelf life. ENIG has excellent corrosion resistance, it is good for aluminum wire bonding, excellent for fine-pitch technology, excellent solder-ability and excellent shelf life.
Is ENIG the same as immersion gold?
What is ISP and OSP in telecom?
ISP is internet Service Provider which provides internet connectivity and OSP is online Service Provider they sell online services.
What is the OSP coating process?
It provides a coplanar surface, well suited for tight-pitch pads (BGA, QFP). The OSP finishing process is composed of three major steps, including pre-cleaning and making the PCB board ready for smooth OSP coating application: Clean: Organic contaminants such as oil, fingerprints, oxidation film etc. are removed to get a clean PCB board.
What is OSP finish on copper?
That’s what this article aims to tell you. OSP is short for “organic solderability preservatives”, and it’s also called anti-tarnish. It refers to a layer of organic finish generated on clean and bare copper by adsorption. On the one hand, this organic finish is capable of stopping copper from being oxide, thermal shock or moisture.
What is OSP PCB surface finish?
OSP PCB Surface Finish–What is the OSP of PCB? OSP includes the process of treating the surface of the printed circuit board (PCB) copper foil with regards to the RoHS instructions. Organic Surface Finish also uses a water-based organic compound that rusts in a typical setting.
What does OSP stand for in chemistry?
From Wikipedia, the free encyclopedia (Redirected from Organic Solderability Preservative) Organic solderability preservative or OSP is a method for coating of printed circuit boards. It uses a water-based organic compound that selectively bonds to copper and protects the copper until soldering.
