SMT(Surface Mount)

QSC has two complete SMT production lines plus a SMT prototype area.

We do BGA’s, QFN’s, 402’s and fine pitch down to 0.4mm.

We have a Glenbrook X-ray machine and an endoscope to insure process quality on QFN’s and BGA’s.

Our SMT lines are specifically designed for fast and easy programming and setup. This keeps customers’ NRE costs low.


At QSC, we like doing THRU-HOLE!
We are good at it. And with our low shop rate, we are very competitive.

We can do ROHS or leaded assemblies.ll of our workstations are ESD safe.

Our standard is IPC Class II, but we also do Class III.

We are customer friendly with our documentation requirements. We can use electronic files or just a sample and a bill of material.

Standard lead time is two weeks from complete kit. However, we can be flexible in this.


A good percentage of QSC’s revenue is from doing repairs or upgrades of products from China.

Our flexible, skilled team can do SMT, thru-hole, or mechanical modifications.

Box Builds/Potting/Conformal Coating

QSC Systems offers Box Builds, Potting, and Conformal Coating

A good portion of our business includes giving customers completed products.

We build the PCB assemblies, test them and then integrate the assemblies into a final product.

We can pot with 3M Scotchcast or customer specified potting, using a vacuum pump to eliminate bubbles.

We do conformal coating for the UL, CSA or harsh environment requirements (not for Mil Spec requirements. We keep it simple to save you money.

At QSC, we also offer wire harness assemblies as well as chassis builds and modifications.

For testing, QSC Systems offers:

– Basic power up test to full functional testing using oscilliscopes, function generators, power supplies, digital multimeters, or we can use equipment supplied by customers.

– Programming of ICs

– Benchtop board level testing to chassis integrated full system test.
We will work with customers to develop test & calibration procedures.

We can functionally test and then troubleshoot to the component level.
