IPC-A-600 2.9.3 I am sure this requirement is also reflected in IPC-6012A Solder Resist on other conductive patterns (SMT land patterns included) < 1.25 mm pitch shall not encroach both sides of the land or exceed 0.05 mm > 1.25 mm pitch shall not encroach both sides of the land or exceed 0.01 mm -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of West, Jim Sent: Wednesday, September 24, 2003 3:33 PM To: [log in to unmask] Subject: [TN] Silkscreen in solder pad Hi, Is there a IPC standard for how much, if any silkscreen can overlap a solder pad? What process is recommended for cleaning a solder pad with silkscreen overtop of it? Examples I have are silkscreen on 0805 pads halfway through it, and some with silkscreen just barely touching.
