| We currently use HASL on all of our boards and I would like to move to something else. I have sampled some boards with Entek OSP and I loved it, the problem is we have plated mounting holes on just about every board we make. Does anyone have info

How to choose PCB finish? It depends your product application.

I does depend on the level of technology of the PCB. RoHS-HASL for basic products and Silver Immersion for a flat finish, are my preferred.

Hi there, Could someone please tell me diferences and possible benefits that are found when using silver as a pcb finish as opposed to HASL. I've already tried the archives without much luck. ta much, jack

Curiously... Shelf-life of the plating alternatives has been mentioned several times as a potential issue in these discussions. Tell me is there a market for a simple plastic packaging which could extend shelf life (and hence solderability) of these

Hi Jack, I once tried this finish ( without changing any process parameters ) and encountered wetting problems even in the first reflow process. It was thought as cheaper alternative to Ni/Au we use for planarity reasons. Heard of the same problems

Jacqueline, Asuming you mean immersion silver: Advantages - Very flat finish compared to HASL, more easily solderable than bare copper with OSP and more process tolerant than this in our experience, reasonable shelf life, cheaper than immersion gol

Hi, Recently, i found a company called "jlcpcb". It’s very cheap 10pcs boards. 1.2mm thick, 1-OZ copper, 6/6-mil outer (0.1525mm) just cost $2 Cheap price and lots of options regarding board thickness, colour, etc. None of my boards have ever had a

Why do PCB traces need a surface finish? On microstrip (top/bottom) the solder mask does not help
