Detailed Description

Padstack definition containing drill dimensions and a table of per-layer pad/antipad/thermal components.

The component table has fixed technical layer slots (solder mask, paste mask, etc.) followed by per-copper-layer groups. Drill location is version-dependent (m_Drill for pre-V172, m_DrillArr for V172+). Slot dimensions for oblong drills are stored as (primary, secondary) not (X, Y), requiring orientation correction based on the copper pad aspect ratio.

Member Enumeration Documentation

◆ LAYER_COMP_SLOT

enum ALLEGRO::BLK_0x1C_PADSTACK::LAYER_COMP_SLOT

Component table layer offsets In the component table's layer section, each layer has 3 or 4 slots, depending on version.

Enumerator
ANTIPAD
THERMAL_RELIEF
PAD
UNKNOWN_GE_V172

Definition at line 1194 of file allegro_pcb_structs.h.

◆ SLOTS

enum ALLEGRO::BLK_0x1C_PADSTACK::SLOTS

Fixed slot indices in the component table.

The fixed slots come before the per-layer copper entries. V<172 has 10 fixed slots, V>=172 has 21.

All fixed slots are technical layers (solder mask, paste mask, film mask, assembly variant, etc). The exact slot-to-layer mapping is version-dependent and not fully contiguous. Verified mappings from WORKLOG reverse engineering:

V<172 (10 fixed): Slot 0 = ~TSM (top solder mask) Slot 5 = ~TPM (top paste mask) Slot 7 = ~TFM (top film mask)

V>=172 (21 fixed): Slot 14 = ~TSM (top solder mask)

◆ m_Components

std::vector<PADSTACK_COMPONENT> ALLEGRO::BLK_0x1C_PADSTACK::m_Components

Collection of components that make up the padstack.

The number of components appears to be fixed by version:

< 17.2: 10 + layer_count * 3
>= 17.2: 21 + layer_count * 4

The first 10/21 components seem to be a fixed set of technical layers.

Then, a set of groups of 3/4 components for each layer.

◆ m_SlotAndUnknownArr

COND_GE<FMT_VER::V_172, std::array<uint32_t, 28> > ALLEGRO::BLK_0x1C_PADSTACK::m_SlotAndUnknownArr

In V172+, elements [0] and [3] hold the true slot outline dimensions (X, Y) in internal coordinate units.

For routed slots (round drill bit routed along a path), m_DrillArr holds only the bit diameter while this array holds the full slot envelope. For punched oblong drills, these values match m_DrillArr[4] and [7].

Despite the name, this is read before the components, not after.
