• Sub-assemblies A, C, F, and G have their screws engaged with standoffs welded to the 0.006” thick stainless
steel chassis, the latter being trapped with tabs to the phone cover
• Sub-assemblies B, C, D, and E use surface mounts (SMT) soldered to the PCB
• The SMT of sub-assembly C has a blank through-hole
• Sub-assemblies B, D, and E use blind-hole threaded SMTs that attach to the PCB
• Screws of A thru E use a tri-lobe-drive. F and G have Philips Drives. All screws have locking patch elements.

• A tri-lobe screw helps assemble the earpiece speaker to the screen body.
• The screw goes through stainless steel stamped joints molded to the plastic earpiece
body, before it engages with welded surface mounts fixed to the screen core via a 0.006”
stainless steel sheet.

• Tri-lobe and Philips screws help assemble the taptic engine, the charging port, and the microphone
altogether to the chassis of the phone.
• Yellow-highlighted assemblies use a screw (Philips or Tri-lobe driven), a super-screw, and a standoff.
• Red-highlighted assemblies use screws engaged into standoffs only.
• Standoffs are mainly welded to the stainless steel 0.006” thick panel, the later being trapped on the
back of the phone cover using tabs and spot welds.

Alternate Solutions
PennEngineering® recommendations
of alternate hardware and cost savings
opportunities.
Section Heading Slide – Do Not Remove
© 2018www.pemnet.comConfidential 32
Clamp Disk FastenerThe Clamp Disk installs onto a pin or a cast post.
Thru-holes allow for removability.
Generates clamp load due to flexing of the downward facing flanges.
Axial installation force.
Along with a surface mount pin, the clamp disk solution could be used in
MAS 3/slide #10 to replace the screws-surface mount nuts combination.
(Patent Pending)

TackPin Fasteners
• Replace screws with TackPin® Fasteners for ductile materials where
serviceability is not needed.
• Simple joining method for permanent joints.
• Many different head designs are available.
• This alternate solution could be used in MAS 2/slide #8, MAS 6/slide # 20,
and MAS 9/slides # 28 and 29.

iPhone X Teardown
• Tri-lobe and Philips-drive screws, super-screws, weld
standoffs, and threaded inserts constitute the main types
of fasteners present in this smartphone.
• A considerable amount of adhesives was used to hold
the screen to the case and the battery components to
the phone chassis.
• Many weld points were present to secure standoffs
attachment to a 0.005” thick Stainless Steel sheet.
• Stamped metal components were mainly used as
latches and latches housings.
