HelpFR4For standard applications the classical FR4 material is sufficientTG150For improved thermo-mechanical propertiesTG170When heat dissipation of a component is higher than normal
HelpSilkscreen is the text on the PCB
HelpLead Free HASLThe cheapest finish available and a good choice for general-purpose boards. One downside to HASL is that the meniscus of the solder causes the edges of pads to be slightly rounded. Surface-mount parts do not sit as flat as they would on an ENIG boardImmersion TinAbsolutely flat, good for fine pitch, good for SMD, good for press-fit but also has a quick oxidation rateImmersion AUThe gold layer is very thin and not intended to provide the main structure of the track, it just acts as a protective coating for the nickel to prevent it tarnishing before it's soldered. Gold is extremely resistant to corrosion so ENIG has several good points: it can be touched with bare fingers without tarnishing, has a very long shelf life, and the pads / tracks are very flat and square-edged - something that can be important for fine-pitch surface-mount partsImmersion AGThis circuit board surface is very similar to immersion tin, with better properties for oxidation and contact applications
HelpNoIf the trace is less than ~1/10 of the electrical length (rise time / propagation delay) then impedance control is not importantYesYes -If the trace is greater than ~1/10 of the electrical length (rise time / propagation delay) ensuring that no errors, noise occurs
HelpThe thickness along with the width of the trace is the determining factor in the amount of current the circuit can carry. The thickness and width of the copper trace is also used in impedance calculations of high speed and RF circuitry.0.5oz/17.5umLow current applications.1.0oz/35umDefault thickness.2.0ozFor high current applications.3.0ozHigh power applications.
