ADVANCED PCB ASSEMBLY

BGA & Fine-Pitch Component Assembly

Precision printing, placement, reflow and X-ray verification for BGA, QFN, CSP, LGA and other high-density packages.

Control below the component

Reliable assembly where solder joints cannot be seen

BGA and fine-pitch packages demand accurate land patterns, consistent solder-paste deposition, stable placement and a controlled thermal profile. Our process combines engineering review with in-line inspection and X-ray verification to manage voiding, opens, bridges and alignment risk.

Process capabilities

Engineering control at every critical stage

01

Land-Pattern Review

Pad geometry, solder mask, via-in-pad and package data reviewed before production setup.

02

Stencil Engineering

Aperture shape, reduction, thickness and step-stencil needs optimized for balanced paste volume.

03

3D Solder Paste Inspection

Paste height, area and volume checked before component placement to prevent downstream defects.

04

Precision Placement

Package recognition, fiducial alignment and placement parameters controlled for dense assemblies.

05

Thermal Profiling

Ramp, soak, peak temperature and time above liquidus tuned to board mass and component limits.

06

X-Ray Verification

Hidden solder joints assessed for alignment, voiding, bridges, opens and head-in-pillow indicators.

Frequently asked questions

Planning a fine-pitch assembly

What information helps you evaluate a BGA build?

Please provide Gerber or ODB++ data, BOM, pick-and-place files, assembly drawings, package datasheets and any acceptance criteria for voiding or X-ray inspection.

Do all BGA assemblies require X-ray inspection?

Because BGA joints are hidden, X-ray is strongly recommended for first articles, new processes, rework and applications where joint quality cannot be verified visually.

Can you support prototypes and production quantities?

Yes. The same engineering controls can be applied to prototype, NPI and repeat production builds, with inspection depth adjusted to project risk and requirements.
