Ay naku naman,,, lead-free soldering should not be our worry for our hobby, altho it helps, a little. Kasi the concern is the disposal of these leaded materials when the time comes. Dito sa Pinas, we are so polluted that for our use, konti lang ito compared to the toxic problems nationwide.
4.Soldering Iron station,temp controlled,SMD tip,medium tip at High Power Tip(chisel type),mas ok madami kang tips para sa pagrerework at paghihinang ng SMD,meron hakko clone sa e-gizmo mas madaling uminit kaysa sa original hakko,sa quiapo naman AEOLUS meron din clones ng Hakko soldering station,better to invest dito para di maworntout yung PCB mo due to uncontrollable temp.7.Hot-air(optional) at capton tape-gamit din sa pagrerewok lalo na sa SMD at BGA types na board.9.Desk Lamp/Third Hand Too with manifying glassl-para sa critical na pagaasemble/rework.10.Camera with macro(optional)-mas ok kung nakazoom kung mag FA ka sa masyadong complex na board.
I recommend Fluke with true RMS reading for your choice of DMM. Expensive but you won't regret it. Agilent is also a good choice but more expensive.
To answer your questions: b) You can maybe get good grounding from a GI pipe, but it's not a guarantee. Or look for the an A/C receptacle if the 3rd slot is actually grounded. Use a neon tester to check.
one of the versatile and most usable tool on hobbyist bench is the digital meter or multimeter. What is the best digital meter for :1. hobbyist - general use, dapat mayroon na testing sa capacitor at inductor, iyong iba mayroon na Temperatureisama na din ang applications sa2. precission - for precise measurement up to 5 digits.3. Testing with Automation na mayroon na din data log capability
