Hi Mark, Look on the bright side, if you want to change from HASL you've got the lead free issue which will allow you to evaluate all other finishes, and find the best one for you. Dave, have you seen any unleaded HASL finishes & any issues arising

Hello, Does anyone have experience with the PCB assembly of 0.5mm pitch chip scale packages with HASL finish? Characterization data that you can share? Tribal knowledge has it that the height variations of the solder prevent the use of HASL for fin

Are there any photos available of what good HASL finish looks like as opposed to not desired? I'm looking for something to use as an aide in inspection becasue sometimes boards at our facility are received with HASL where the solder is excessive cau

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

check the solderablity of the board and the thickness of the solder before screening, if you are using HASL finished boards.

The assembly is HASL finished. The colour of the solder mask is green, ( sorry I dont know the technical name ).The flux is No Clean (Koki JS3000)which is seeing a preheat temp between 90-100degCel. The solder pot is set at 250degCel and is 63/37.

I do not recommend using a HASL finish, you will have a very tough time printing repeatably.

I did not get that info. We sent them back and the vendor ran them through HASL finish. They processed very well after that. Thanks to everyone for the help. mk

I would imagine it is lead free HASL finish board from the sounds of it am I right. Cheers Greg
