easiest way is to weigh an empty board and then weigh a printed board, best to do 10 or so and take an average.

I've seen where a new person comes on with some strange problem. Then someone else new comes on and says that the perfect solution is siplace boards. And for a while it seemed like Siplace boards were the solution to every problem. Or maybe they we

I am new to the board so be gentle with me. There are standards such as IPC-610 for PCB assembly, IPC-600 for bare boards, etc. Is there a "standard" for electro-mechanical assembly? Is there an IPC standard or any other industry approved standard

I need to solder SAC/HASL PC boards in a NON ROHS process (Tin Leaded solder paste and profile + Tin leaded components) Can I do that?? Regards, Eyal

We use immersion tin boards and ENIG with Sn63Pb37 with no problems. We did have to tweak the profile higher with ImmSn though.

Tell the board shop to increase the cure temp of the resist as it is undecured especially if you have waxy/greasy resiues on the board and a brown tar like substence in the solder wave itself. If undercured then solder will not flow off the resist pr

Let's narrow this down. Questions are: * Are you putting the proper amount of solder in the board with your stencil print process? * If you are putting the proper amount of solder in the board, where is the solder going? Pick one and then fill-in th

We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.
