Hi anyone knows what is the minimum copper foil thickness available across the industries to make PCB surface. Intention is to achieve 23 microns of finished copper thickness in a 0.3mm thickness PCB. Ideally if 3 microns plates are available, additi

Some people involved in PCB assembly process claim that SMD components reflow soldering problems are often caused by traces running under a component. According to this claim, trace (or any copper) covered by solder mask and placed under SMD componen

okay, add more flux first and try, pcb surface is not copper already, if more flux helps, than your pcb surface should be ok if not than mehanically cleaning the surface please, (like your car at home 'pol�roz�s-hungaian' I do not know the engli

Hi, We have been manufacturing a PCB, however it's been quite tricky to profile, as the edges of the PCB are reflowing before the center of the PCB. I have looked at the design, and there is a small power plane for 2.5 Volt in the center of the PCB

Thanks Steve.The bent we are seeing is at the location without any component .It is a small and long pcb,one side fully loaded with component .Thebother side got no component. We can manually bend the pcb at the side without the component. All the la

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder

No we have a battery spring that is soldered directly to a PCB (standard tin plated copper PCB). The Battery spring supplier (and I have no confirmation he makes them or buys them) claims they are tin plated. When trying to solder to them it is very
