Drilling is very
critical for printed circuit board
process. M C P L is using Dynamotion
five spindle machines for medium to
high volume production. Lasers do
a comparative analysis to the NC drill
data, verifying drill bit diameter
while checking tool length and run
out (wobble). With drill speeds up
to 125000 RPM with 99 tool magazine
program ,Dynamotion are not only precise
and efficient, but drill some of cleanest
holes in the industry.
We are also equipped with excellon
Mark IV,V,VI and Tru-drill 104/105
drilling machines. Fro small lots
,we utilize Alpha drilling machine.
They feature auto-load and unload
for lights off operation .These are
excellent for prototypes due to their
quick setup and unsurpassed speed. |

Our adoption of world
class Shadow process gives us an advantage
over others because of its reliability
,focus and perfection. Shadow-holes, and
other vias , conductive colloid 2 is an
alkaline aqueous dispersion used to make
through-holes, and other vias, conductive
for subsequent copper electroplating.
Shadow process in environmentally advantageous
as compared to other metallization process.
Benefits include, no metal chealators
, less rinse water usage and ease of operation. |

The
process gives perfection to copper build-up on
the panels. With vertical synchronized and conveyrozied
movement with educator flooding system establish
uniform copper plating on the holes and surface.
This type of process adoption is for the first
time in India. |

Panels fed from hole
prep through the wall to clean rooms are
processed through auto cut sheet laminators
outfitted with micro-clean and anti-static
tacky roller systems. Dry film is applied
at this point. |

Imaging
is performed in clean room utilizing Mania Max
9000 exposure unit that is outfitted with automatic
registration systems featuring vacuum hold-down
with excellent registration capabilities. Room
is temperature and humidity controlled. |

Copper/Tin
plating is eductor based, allowing high aspect
ratio plating with superior copper distribution
characteristics and surface to hole ratios. High
output rates coupled with low labor content is
and added plus. |

From
plating, the process panels travel to film strip,
copper etch and tin stripping. PLC and in-process
sensors provide excellent real time control of
the process. First day film is stripped to expose
unwanted copper on the panels. The tin is also
then stripped and the copper is cleaned and prepared
for solder mark application. |

LPI is automated and processed utilizing DP-1000
and DP-1500 systems. We can process any process
any types and color masks. This unit applies LPI
ink with computer controlled squeegees, and then
tack cures the in tunnel over preparing the panel
for imaging. |

Once the panel is
exposed the panels are moved through IS make developer.
PLC and in-process sensors givens excellent real-time
process control and gives perfection to the developing
of circuitry of customer's requirement. |

Horizontal Hot Air Solder Leveller
|
![]() |
| |
One of the first of its kind in India. Alchemy
computer aided solder leveling is designed to
achieve improved surface planarity, excellent
solder distribution and finish. The reduced solder
contact time and convection preheat reduces thermal
shock and flux absorption. Computer aided process
control gives high reliability and consistency
of product. The system gives increased capacity
with typical throughputs of 2000 panels per shift. |

With a number of Mania ,L & M and U-Tron electrical
test machines. M C P L make sure that each and
every board are tested for high quality and trouble
free .L & M machine with auto loader, un-loader
and auto fixture filling capability gives reduction
of man power and high accuracy testing of the
boards. We have 70mil base gird testing capability.
This will help us to deliver trouble free boards
to out esteemed customers. |
