Re: Use of solder paste for leaded thru-hole parts????? | 7 July, 1998

Thanks Earl. Well following is the data regarding the product. 1. The panel consists of 21 boards. 2. The surface I mentioned would have 3 SMds and 1 T/hole connector. 3. PCB thickness is 55 mils and the width of the hole on the PCB for the thru-hole connector is 40 mil. 4. Leads of the connector are rectangular with 10 mil thickness and 24 mil width, with a pitch of 90 mil between the leads. 5. Two of the SMT components are 10 pin relays with a pitch of 100 mil (0.1") and the other one is 16 pin SOIC with a pitch of 50 mil. 6. The stencil which we are using right now for SMDs is 8 mil thick. Because of the space constraint we cannot think of a step down stencil. Any advice....??? Regards Upinder ===============
