Bakelite Synthetic Stone Wave Solder Pallet Jigs Solder Carriers Fixture

III. Application

1. Support thin baseboard or soft substrate circuit board

2. Carry an irregular shape solder pallet

3. Use multi-pak panel design to improve production efficiency

4. Prevent the deformation of the solder pallet during high temperature reflow soldering process

5. Smoothly surface, good endurance, applicable for Teflon spray painting

6. Avoid gold finger contamination by human contact

7. Protect bottom side SMT components during the wave soldering process

8. Prevent the deformation of the baseboard during the wave soldering process

9. Standardized the width of the production lines, eliminate the width adjustment of the production line

10. Prevent baseboard being contaminated by the overflow of tin

Durostone for Wave Solder Fixtures

Name: Durostone Sheet

Color: black

I. Description

Durostone is a heavy-duty glass fiber reinforced plastic which offers extreme strength and excellent electrical, thermal and chemical properties. It can keep its mechanical strength, smoothness and original color when continuously used under the temperature of 280°C (max. working temperature below 385 degree 10~20sec).

In addition, durostone have the advantage of easily machining, high intensity and can be easily machining into special mechanical parts.

II. Main Characteristic

1. Normal working temperature at 325 °C, operating temperature up to 384 °C

2. Less distortion, low thermal conductivity

3. Superior dimensional stability, Long life

4. High temperature resistance
5. Resistance to chemical corrosion

6. High mechanical strength

7. Good machinability (low density)

Process Suitability

The viability of this process route crucially relies upon being able to estimate the number and distribution of PTH components

which CAN'T be processed (with and without glue dotting) - These will have to be miniwaved or hand soldered.
which are likely to be poorly soldered - These will require further inspection and manual touch up.

This estimation may be done in three ways

If a PCB is available (preferably populated) - our sales engineers can rapidly evaluate your board.
If PCB design data is available we will process, analyse and remotely assess it.
You can do it using the rules presented below - our customers quickly find that the above two methods are easiest.

Gerber, Excellon and other data required

Pin Land to SMT pad clearance evaluation

The two figures below each show part of a CSWSC in plan and section views. The right hand figure shows that more clearance
is required when the connector orientation is perpendicular to the wave.

PTH Components Located Parallel to direction through wave

The clearance required between the pin land and SMT pad can be made quite
small, as the solder does not have to flow "under" the component pockets.

PTH Components Located Perpendicular to direction through wave.

A larger separation is required due to the solder having to flow "under"
component pockets.

Working your way around the underside of the PCB, identify which components
are parallel and perpendicular to the wave and assess the solderability of each
PTH connector by comparing the actual separation against the graph right.

Ideally you want to be above the line in all cases.

FAQ

(1) Discount price yes&no ?

It is depending on the volume. The larger the volume is, the more discount you can

enjoy.

(2) Why your price is a bit higher than other Chinese suppliers?

To meet the requirement of different customers and areas, our factory manufactures

various kinds of quality for each item at a wide range of price. We can offer the

products of different quality levels depending on customer’s target price and quality

requirement.

(3) If I can get a sample ?

For existing samples (sizes not larger than 300*300mm) can be sent free of charge

but you just need to bear shipping charge, or you can provide your DHL, FEDEX,

EMS, UPS courier account number to us.

For bigger sizes, or customized samples, it depends on negotiation.

(4) If you can guarantee the quality of mass production is same

as the sample sent to me before?

Quality is our culture, is our life. We believe our products will give you a surprise.

Our warehouse staff will leave another same sample in our workhouse, and marked

your company name on it, which our production will be based on.

(5) How can you deal with quality issues after receiving the goods?

1) First you take photos of unqualified goods and then our sales staff will send

them to Manufacturing Department to verify.

2) If the problem is confirmed, our sales will explain the root cause and take

corrective actions in coming orders.

3) Finally, we will negotiate with you to make some compensation.
