• four stage cascade rinsing, followed by drying
• etching rate is controlled to 0.6um• Process control etch rate sampling is
carried out on a per shift basis.• Loading and unloading is fully
automated.

AOl Process - Orbotech
• two AOI machines• three offline verification stations• the inner layer is scanned, barcoded,
interlaced, and then sent to fault verification
12/12/2018
Alternative Oxide
• line speed: 3.5 meters/min• Etch rate: 1.5 +/- 0.3 um• maximum size: 21.5” x 24.5”

Build Up
• all inner-layers are visually inspected at build up
• layers are built up with small rivets and flattened
• all multilayers are then 100% inspected by X-Ray
• any panels showing mis-registration will be rejected
• all operators wear cleanroom garments
12/12/2018
Lay Up Stations
• all panels are built on large format stainless steel panels
• panels are built free with oversize foil -for example, a 24” x 21” panel would be built four panels per page
12/12/2018
Presses & Press Capacity
• large format presses with auto-load &unload facility
• four presses all with 8-openings• capacity: 5000 panels per day based on
a 24*18” 1.6mm panel• 320 panels per press load
12/12/2018
Press Control
• all presses have chart recorders for each individual press and platen
• the data is available from each press cycle recording both platen & product temperature
• buffering is 160gsm Kraft Paper• kraft paper is not reused
12/12/2018
X-ray Drilling
• four ADT-900 X-ray drill machines• all four machines optimised in both X & Y• all panels are interleaved before and after
drilling
12/12/2018
Routing
• two route machines with four spindles each• programs all ensure radius corners • typical height is 5 high for a 1.6 mm panel
12/12/2018
Edge Milling
• all panels are edge milled• four individual “v” blades for cutting each
edge • maximum panel thickness for edge milling
is 3.2mm
12/12/2018
Bonding Inspection
• all panels are checked for 100% surface defects, including pits, dents, resin spots or creases
• a thickness check is also performed using deep throat micrometer
• tooling hole diameters are verified using a plug gauge
• outer copper is verified using a copper scope
12/12/2018
Drilling
• 240 drill spindles• capacity: 8000 panels per day• process runs 24/7 • mechanical drilling • minimum hole size 0.15 mm
12/12/2018
Drilling
• a first off x-ray inspection is carried out prior to batch processing
• for batch inspection the bottom panel of each stack is x-ray inspected
12/12/2018
Spindle Accuracy
• all spindles are checked for accuracy twice per week
• reports are available for drill accuracy• hole positional checks are verified by AOI
inspection
12/12/2018
Hole Checking
• after drilling all panels are processed through a high pressure rinse and then inspected through the automatic hole for missing/blocked holes
