USE ESD-Safe Work Station / Work Bench / Table: Yes, repairing of any smartphone, mobile phone, tablet, laptop or any other such electronic gadget must always be done on an ESD-Safe Workbench. An ESD-Safe work bench is nothing but a table made up of ESD-Safe material with ESD-Safe Mat on the area where actual repairing is done. The whole table including the ESD Mat and the person doing the repairing job are all grounded properly. This prevents the gadget or mobile phone from any potential damage due to static electricity. Now, static electricity is unwanted electricity or flow or electrons from one body to another. These negatively charged electrons can cause damage to sensitive electronic components mainly SMD (Surface Mount Devices).
Such work stations are well equipped so that all your tools of regular use are within your arms reach and at appropriate place
