ACME PCB Assembly has provided (Ball Grid Array) BGA assembly, BGA rework, and BGA reballing service for Printed Circuit Boards since 1994. Having 20+ years experience behind us, we have extensive knowledge on how to assemble high quality (Ball Grid Array) BGAs. We have experience with everything from Micro BGAs to large size BGAs (55 mm), and ceramic BGAs to plastic BGAs.

BGA assembly is a type of SMT process, which is used for Printed Circuit Boards. It allows for the customer to have more room for the PCB layout.  Ball Grid Array (BGA) packaging is a method for reducing package size and integrating a greater number of functions on a single chip module. BGA (Ball Grid Array) also replaces solder balls on the component underside for SMT mounting.

ACME PCB Assembly has a quality system for BGA assembly, the BGA will be received and inspected, and kept in a 40-degree Celsius storage with a 1% humility baking oven to make sure the BGA is good condition before assembly.  We inspect the BGA with a 3D X-ray, and make sure the void is under 25% of the total solder ball diameter. By using the X-Ray inspection process, we can eliminate the soldering problem on the board, such as solder bridging and insufficient ball melting.

We also add an additional layer inspection after the X-Ray inspection is done; using the ERSA scope to inspect the solder ball on the underside of the BGA so that we are sure the profile is correct; we assure you excellent quality during the BGA assembly process.  Some BGA assembly boards have VIA connect to the BGA pad, the best condition for that is have a VIA epoxy plug, and have the solder mask on the trace, so that solder is not wicked to the VIA and cause the solder to function insufficiently during the BGA assembly process.

By having ACME PCB Assembly do the BGA assembly prototype with or without Stencil will save you as the customer on assembly costs.
