二、应用操作指引

基板表面处理

 

化锡板推荐使用超粗化

化金板推荐使用超粗化、火山灰或喷砂

OSP板和喷锡板可以使用超粗化、火山灰、喷砂或磨刷

 

 

开油

 

主剂与固化剂按3:1混合,添加适量稀释剂,搅拌5-10分钟。静电喷涂,预喷粘度一般控制在25秒,主喷粘度一般控制在50秒。水平低压喷涂粘度一般控制在40-60秒,依客户设备需要。

 

 

静置

 

10-20分钟,使油墨充分排出开油时产生的气泡,但不超过24小时。

 

 

喷涂

 

走板速度及喷枪压力等条件,依厂商要求。

 

 

预烤

 

 普通隧道炉:温度70-75℃,时间40-45分钟

 红外隧道炉:各公司可以根据自已设备情况,主要温度可以控制在80-120℃之

 间,时间在2-5分钟之间依需要调整。

 以常用六段温区炉为例,可分段设为85℃-95℃-95℃-95℃-95℃-70℃,速度 3.5-4m/min,时间4-5分钟

 

 

冷却

 

放置20分钟以上使板材充分冷却,但停放时间不超过24小时。

 

 

曝光

 

曝光能量一般在400-1000mj/cm2 ,使用21级曝光尺保持感度在10-12格之间

 

 

静置

 

20分钟以上,但不超过24小时

 

 

显像

 

  压力2.0-2.5kg/cm2浓度1wt% Na2CO3,液温30±2℃,显像时间70-90秒

过显影缸后,再用2.5-3.0kg/cm2喷淋压力25℃左右的市水清洗45-60秒,使用2组以上海棉轮吸水,40℃以上热风吹干

 

 

热固化

 

沉金板、沉锡板:150℃×50分钟;

抗氧化板、喷锡板:150℃×60分钟;

厚铜板(2OZ及以上)分段烤:第一段75℃×120分钟、

第二段100℃×30分钟、第三段150℃×60分钟

Processing instructions

Pre-treatment

 

IMT recommended use superbond

ENIG recommended use superbond pozzolana or sand blast

OSP and HASL can be superbond, pozzolana, sand blast or polish-brush

 

 

Mixing

 

Main agent and hardener agent in 3:1 mix, add appropriate thinner, stir or shock 5-10 minutes. Electrostatic spraying, pre-spray viscosity is generally controlled in 25 seconds, the main spray viscosity is generally controlled in 50 seconds. The viscosity of horizontal low-pressure spraying is generally controlled in 40-60 seconds, depending on the needs of customer equipment..

 

 

Hold time

 

Hold time: within 20min after printing, But not more than 24 hours

 

 

Spraying

 

Transfer speed、Sprayer stress、Sprayer calibration in accordance with the equipment requirements

 

 

Pre-cure

 

Normal tunnel oven: 70-75℃, time of 40-45 minutes

IR tunnel oven: You can according to your equipment condition, main temperature can be controlled between 80-120, the time between 2-5 minutes

EXP: six zones IR tunnel oven, setting 85 ℃ -95 ℃-95 ℃-95 ℃ -95 ℃-70 ℃, speed 3.5- 4 m/min, times: 4 to 5 min

 

 

Laminate mask film

 

Hold 12-30min to cool down enough

Laminate mask film in vacuum under 40 mmHg

 

 

Exposure

 

400-1000mj/cm2 (on resist surface) to 10-12 level

vacuum under 650 mmHg

 

 

Hold time
