我查到的常见嘉立创免费/优惠门槛里，核心尺寸条件基本都是：
- 1–4 层板
- 长宽在 10cm × 10cm 以内
- 常见活动里会写成 5 pcs / 单片
- 一般还会附带“常规工艺”限制，比如标准板厚、常规表面工艺、标准铜厚等
- 很多活动/免费券还会带上 新用户、指定下单渠道、月度次数限制 之类条件
你的板子是：
- 100mm × 70mm
- 4 层板
从外形尺寸看，它是落在“10cm × 10cm 以内”这个常见门槛里的。
也就是说：
也就是说：
- 尺寸本身：符合常见免费/优惠尺寸区间
- 层数本身：也符合常见 1–4 层活动范围
能不能“免费出样”，不只看尺寸和层数，还取决于这几个条件是否同时满足：
- 你账号当前有没有对应免费券 / 新人活动资格
- 是否要求常规工艺
- 是否限制板厚、表面处理、颜色、拼板方式
- 是否要求 5片内、单片、不拼特殊工艺
- 活动是否还在有效期内
- 如果按常规 4 层板工艺下单，这块 100×70mm 在“常见活动尺寸”里是有机会命中免费/优惠的
- 但我不能仅凭尺寸断言一定免费
- 最可能的情况是：
- 尺寸/层数 满足活动外框
- 最终能否免费，要看你账号和工艺选项
- 尺寸：符合常见免费打样尺寸门槛
- 4层：也在常见活动支持范围内
- 是否一定免费：不一定，要看账号资格 + 工艺是否标准
如果你愿意，我下一步可以继续帮你做两件事之一：
- 按嘉立创常规免费/低价工艺约束，反推你这块板哪些参数别乱改
- 直接整理一版“下单前检查清单”，让你下单时更容易命中优惠。

You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors.
