Bruce I�m with yall. Designers and fabricators say �pins�. You say: * BGA pins are 1mm [0.039�] pitch. * BGA pads are 0.4mm [0.0157�] diameter. * BGA pins are 0.6 mm [0.024�] side-to-side. * Board thickness is ~0.4 mm [0.015�] First, as you can

I don't entertain the forum like JAXSUN. I never have played games but for some humorous insights. I, when participating, never complained until management provided only more incentive to advertisers than forum members. That said, the following is a

Currently, we are baking any PCB before process on SMT, the 'reason' is to dry any possible humidity that could be inner the PCB, it does not matter if the PCB is multilayer or not. We bake PCB's at 107C for 4 hrs and the board must be process into n

SMT-ypw: Does PWB supplier start to implement PWB drying packaging? B3: YES! The fabrication of the PCB involves a series of wet processing that requires counter-measures to remove moisure. While some of the PCB processes also include bake cycles th

Thanks for replying Mr BoardHOuse. The product has to be RohS compliance. Surface finished is something that I am still considering and currently looking at either OSP or Immesion Silver. In short whatever combination that can produce high reliabili

Correct preheating of the assembly is critical. Check with your flux manufacturer regarding the recommended topside pcb temperature as it enters the first wave. It is important that this temperature be achieved without burning the flux on the bottom

If you have some tool which can be convenient for repairing component mounted with lead free process, please email to me, I am interested in them very much. In my opinion, to repair a SMD component is not difficult. The most important thing is how

Your question may be answered in two parts. First, if you are using a water soluble (OA) paste, then water is an excellent �solvent�. Water, in one way or another, is used to clean all fluxes and pastes from PCB�s. In some cases, a chemical is add

Are we talking a professional device that takes something like the Squink/Voltare/EX1 projects on Kickstarter and delivers something that could be confidently used commerically? Would it be strictly a prototyping tool or would it also be suited to lo
