IPCB_PrimitiveVia.setState_SolderMaskExpansion() method

This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Set the property state: solder mask / paste mask expansion

Signature

function setState_SolderMaskExpansion(
	solderMaskExpansion: IPCB_PrimitiveSolderMaskAndPasteMaskExpansion | null,
): IPCB_PrimitiveVia;

Parameters

Parameter	Type	Description
solderMaskExpansion	IPCB_PrimitiveSolderMaskAndPasteMaskExpansion | null	Solder mask / paste mask expansion

Returns

IPCB_PrimitiveVia

Via primitive object

Example

// 1. 生成本次运行专用的坐标，放置一个默认扩展（遵循规则）的测试过孔
const x = 3000 + Math.floor(Math.random() * 100000);
const via = await eda.pcb_PrimitiveVia.create('', x, 3000, 20, 40);
const before = via.getState_SolderMaskExpansion();

// 2. 异步模式下自定义顶层阻焊扩展并提交
const a = via.toAsync();
a.setState_SolderMaskExpansion({ topSolderMask: 4 });
await a.done();

// 3. 从画布重新读取，确认扩展已生效（未设置的底层项返回 null）
const ref = await eda.pcb_PrimitiveVia.get(via.getState_PrimitiveId());

console.log('expansion:', before, '→', ref.getState_SolderMaskExpansion());
