At Topsearch, reliability is one of our top concerns. By employing
top talent and some of the most advanced equipment, we are able
to maintain high levels of reliability. Above and beyond customers
requirements such as SEM/EDAX, IR reflow machine, low resistance
short detection and pressure cooker ,etc.
√ Registration£º
Internal Registration: We take internal registration very
seriously; 100% x-ray optimization prior to drill, we are insured
to meet the customers tightening specifications
 X-ray
Optek£º The Optek
allows us to increase the accuracy of internal registration checks.
The x-ray improves the positional accuracy to 0.5 mils allowing
us to trouble
√ PTH Reliability£º
Buy using Air to Air, and Liquid to Liquid testing, we can insure
that our products are run under the best possible conditions. These
two provide us an additional level of process control, by allowing
us to see, what cannot be viewed by other methods like cross-sections
or solder float. It allows us to fix potential problems before they
turn into quality or reliability issues
Air
to Air£º This temperature cycling provides a gradual ramp
on temperature. This process is most standard outside of the solder
shock
Liquid
to Liquid£º With liquid as the medium the heat transfer is
much quicker allowing results in a much quicker time.
√ Lamination
Pressure
cooker£º The pressure cooker allows us to set the most efficient
and reliable process parameters for each of our material. This machine
is much more effective than solder floating alone.
√
Surface finish£º With
the almost unlimited supply of surface finishes we have, surface
quality requires special machinery.
Wetting
Balance£º To insure good solder ability at our customer's
sites we have purchased a wetting balance machine, this allows us
to proactively prevent problems on the process lines. It helps us
to set process controls, as well as QC sampling
Ionic
Chromatograph£º To measure the level of anionic contaminants
on the surface of the PCB. The in-house control here is to focus
on - Cl , Br and SO4 residue remains on the PCB surface to determine
the cleanliness control.
√ Other
SEM/
EDAX£º We are one of few board shops that own a SEM. This
is not only used for quick and help in troubleshooting, but is also
used for process control, allowing us to derive process parameters
from the high quality pictures
