Reconcile Panel Quantity, Board Quantity, and Assembly Demand

An order for twenty items can mean twenty individual boards, twenty assembly panels, or twenty sets of several different circuits. The arithmetic may be correct while the receiving teams use different units. Define the unit before comparing quantities or calculating component demand.

Eurocircuits’ panel configuration documentation distinguishes panel dimensions, repeat arrangement, and the resulting boards per panel. These are related fields, but none alone identifies the number of finished assemblies required by a customer.

Map the physical hierarchy

Describe the single board, the customer delivery panel, and any larger manufacturing panel used internally by the fabricator. Only use a supplier’s internal production-panel quantity when the order explicitly requires it. It is not automatically the same object that the assembler will receive.

For a mixed panel, list each circuit and its multiplicity. Do not multiply every BOM by the total number of outlines if those outlines represent different designs. Keep nonfunctional coupons and handling features outside the count of deliverable product boards. Show their purpose on the panel drawing to prevent automated counting mistakes.

Use labeled arithmetic

For illustration, ten panels carrying two copies of circuit A and one of circuit B contain twenty A positions and ten B positions. That does not authorize thirty copies of either BOM. State whether all positions are intended for assembly and how unusable positions will be handled.

Reconcile every handoff

1. Check the quotation’s quantity unit.
2. Confirm the purchase order uses the same unit explicitly.
3. Match the approved panel drawing to the repeat count.
4. Calculate component demand separately for each circuit and variant.
5. Record delivered panels and usable board positions distinctly.

Do not assume that nominal positions equal accepted finished units. Any allowance for marked-out boards, partial panels, spares, or overdelivery needs an agreed counting rule. Otherwise the assembler may believe the kit is short while the fabricator believes the panel order was fulfilled.

At receipt, preserve the relationship between the panel identification and its board positions if later separation will remove that physical grouping. The counting record should let production answer both “how many panels arrived?” and “how many units of each product can this material support?” without reconstructing assumptions from a quotation screenshot.
