HP 9030 User Manual

Assembly Access 4-3
Carefully observe the following procedures when disassembling the computer:
• Components, PC assemblies, finstrates, other assemblies and equipment should always be
stored, transported, and shipped in antistatic or conductive containers.
• ESD-sensitive items must never be handled by ungrounded personnel, nor should they ever
be stored on non conductive surfaces or near nonconductive materials.
• Field support should keep all replacement PC assemblies and components in antistatic or
conductive bags. The customer engineer should be grounded when working on products. A
field service antistatic kit is available; it includes a static-free work station, ground cords, wrist
straps,
and board storage space. The failed board should be placed in a static-free bag for
return to manufacturing site.
• Removal of ESD-sensitive devices from an assembly must be done at a static-safe work station
using
all precautions. Suspect or rejected components, PC boards, and subassemblies are to
be treated with the same care as good devices. Otherwise, further damage may result which
prevents tracing the cause of the original failure.
• Before removing devices from protective container:
a. Clear work area of static hazards such as plastic cups, bags, envelopes, and papers.
b. Connect wrist strap.
c. Neutralize charges of ESD protective packaging containing an ESD-sensitive item and of
tools by placing the packaged item
on an ESD-grounded work bench surface to remove
any charge prior to opening the packaging material. Alternately, charges can
be re-
moved by grounded personnel touching the package.
d. Ensure that the computer is properly grounded before inserting ESD-sensitive items.
e. Remove ESD-sensitive item from ESD protective packaging using finger or metal grasp-
ing tool only after grounding,
and then place on the ESD-grounded work bench surface.
• Place PC boards, finstrates, and components on table mat when not in static-shielding bags or
other protective containers.
• Clothing must never contact ESD-sensitive parts. Wrist strap does not bleed off charges from
clothing.
• Personnel handling ESD-sensitive items should avoid physical activities which are static pro-
ducing
in the vicinity of those items. Such activities include wiping feet and removing or putting
on jackets or sweaters.
• Where ground straps cannot be used, personnel should ground themselves prior to removing
ESD-sensitive items from their protective packaging.
• Tools and test equipment used in ESD-protective areas should be properly grounded; hand
tools should not contain insulation on the handles or, if used, tools with insulated handles
should
be treated with a topical antistat.
• Ensure that all containers, tools, test equipment, and fixtures used in ESD-protective areas are
grounded before
and during use either directly or by contacting with a grounded surface.
Grounding of electrical test equipment should
be via a grounded plug, not through the con-
ductive surface of the ESD-grounded work station.
• Do not assume that insulators are fully discharged when placed on a conductive work surface.
Once the insulator is lifted off the surface, it retains its charge.
• All PC boards and finstrates are to be handled only by grounded personnel. If possible, they
should
be held only by the ejectors. If necessary, they can be handled by the side edges.
