Hi there, I have quite a number of problematic bd due to warpage problem. I would like to know the method on how to measure PCB warpage, thus to decide on the dispositon of these boards. Another question, can these warp bd be rework/fix. Is there

Earliar we had problems with board warpage, Much of our problem was due to imbalances in the copper on oppisite layers in brief on a 8 layer board the copper on layer 1 should = the copper on layer 8, 2=7, 3=6, 4 = 5. We added copper to some layers t

A novel epoxy flux EF-A was developed with good compatibility with no-clean solder pastes, and imparts high reliability for BGA assembly at a low cost. This compatibility with solder pastes is achieved by a well-engineered miscibility between epoxy and no-clean solder paste flux systems, and is further assured with the introduction of a venting channel. The compatibility enables a single bonding step for BGAs or CSPs, which exhibit high thermal warpage, to form a high-reliability assembly. Requirements in drop test, thermal cycling test (TCT), and SIR are all met by this epoxy flux, EF-A. The high viscosity stability at ambient temperature is another critical element in building a robust and userfriendly epoxy flux system. EF-A can be deposited with dipping, dispensing, and jetting. Its 75°C Tg facilitates good reworkability and minimizes the adverse impact of unfilled underfill material on TCT of BGA assemblies.
The new system delivers high-speed (5,700mm2/sec), high-accuracy (XY positioning of 3µm at 3?), height repeatability (below 2µm at 3?), and scalable resolutions of 7, 12 and 18µm for boards weighing 12kg. http://www.sakiglobal.com/automated-optical-i
