Plan ESD circulation-rack WIP routing with defined handoffs, board sequence, temporary-buffer rules, ESD evidence, and inputs before selecting a model.
Start with the live ESD Rack category and make the process requirement specific enough for quotation review.
Part 1. Temporary-storage decision
A rack belongs at a process point when boards predictably wait there and the wait has a named next action. An unassigned table is a signal to document the handoff before choosing equipment.
Part 2. Open storage versus magazine racks
An ESD Rack here means open slotted storage for static-sensitive items. It is not a PCB magazine rack.
Magazine racks are enclosed holders for loader and unloader automation. Their interfaces and handling logic are outside this article.
Part 3. Slots and board envelope
Slot spacing must be checked against the handled board or panel envelope rather than copied as a universal value. Record edge condition, packaging, orientation, and access motion.
Confirm the relevant model row in the quotation and sample-use review. An empty fixture does not prove loaded-board fit.
Part 4. Access and handoff
Place the open face where the responsible operator can load and remove work without crossing a walkway or machine-access zone. Keep the next action and oldest waiting work visible.
Record the process handoff, owner, status method, and exception route. A controlled position needs these operating details.
Part 5. Temporary WIP rule
Temporary storage needs a cap and clearing trigger. Without them, an orderly rack can become hidden long-term storage.
Assign exception clearing to one role and revisit the rule when product flow changes. This is a workflow rule, not a performance claim.
Part 6. ESD evidence
ANSI/ESD S20.20-2021 provides program context; it does not approve an individual rack. The buyer defines the test method, evidence, and acceptance approach.
Use the ESD Rack category to identify families, then request a quoted-model review. Do not infer dimensions, load ratings, materials, MOQ, price, or lead time from a family label.
Part 7. RFQ and sample review
Send board envelope, slot and access requirement, handoff, temporary rule, ESD evidence request, and acceptance criteria. The supplier can then map the request to a model review.
A sample-use review checks real-board insertion, removal, operator reach, status visibility, and site constraints. It also confirms open-rack storage rather than magazine-rack automation.
For product recommendation, start with the Sanwei ESD Rack category and request a quote-confirmed model review.
Fit Boundary
Documented temporary handoff supports a rack requirement. Loader or unloader handling needs magazine-rack evaluation. Uncertain fit needs sample review under site rules.
Часто задаваемые вопросы
What is an ESD rack with slots?
It is open rack storage that holds static-sensitive work in slots for a defined use.
Is an ESD rack with slots a magazine rack?
No. This article covers open storage; a magazine rack is an enclosed automation holder.
How should slot spacing be specified?
Provide board envelope, edge condition, packaging, orientation, and access requirement.
What should a temporary SMT rack position record?
Record handoff, owner, access direction, status method, storage cap, and clearing trigger.
How can a rack avoid becoming permanent storage?
Set a cap, define the next action, assign an owner, and make exceptions visible.
What ESD evidence should be requested?
Request the test method, evidence, and acceptance criteria required by the buyer program.
What should a sample-use review check?
Check real-board insertion, removal, access, status visibility, process flow, and site constraints.
